I don't get these event log entries so I can kind of only speculate at this point.

If I were to fathom a *GUESS*, do you by chance have your Supermium sitting in the PROGRAM FILES directory?

If so, MOVE IT SOMEWHERE ELSE, but don't move it to any folder that is "protected" in XP by default.

ie, ANYWHERE *except* any of the following  --

C:\Windows
C:\Program Files
C:\Windows\System32 (you're on x86, x64 users would also exclude C:\Windows\SysWOW64)
C:\Windows\Temp
C:\Windows\Prefetch
C:\Documents and Settings\<Username>\Local Settings
C:\Documents and Settings\<Username>\Application Data
C:\Windows\System32\config\
C:\Windows\System32\config\systemprofile\
C:\Windows\WinSxS
C:\Windows\Logs
C:\Windows\Help
C:\Windows\Installer
C:\Windows\Media

I tried to run Supermium in XP x86 but it would not even launch for me.

Six or more chrome.exe's populate Task Manager but no Supermium ever appears.  I had to terminate via Task Manager.

But even that was enough to WITNESS your event log entry regarding garbage collector.

But this is also a tad confusing, I thought that an EXTENSION needed to be installed?  I couldn't even launch Supermium in XP x86 to even add any extension.

That said, I don't own any XP x86, all of my real XP machines are x64.  So this was inside a XP x86 VM (where ek3-whats-his-name works fine but Supermium has never really liked).

Off-topic, but your lack of a visible window could be caused by a known issue on XP, which I reported here.

It seems to be hardware-related, with some GPUs.
That causes what I described as a 'ghost window', which is present but invisible!
Try with the --disable-gpu switch, that might fix it.

Eureka!  That was it!

But I'm still *not* able to get the event log issue.

Not on XP x64.  And not on XP x86.

but... fine i'll give up then... it's impossible to ever stop this stupid crap from flooding the event log thing forever.

I'm going to give up also.

But for the exact OPPOSITE reason.

I'm not able to get the event log flooding - which is a "good thing", but why am I *not* getting it when the OP "can't not" (double negative) get the event log flooding ???

Scratch that.  I *can* reproduce.  I have to keep it open for longer than a few seconds before closing.  I was launching and exiting, launching and exiting, launching and exiting - no event log.

But if I *wait* a minute or so, then exit, yeah, event log EVERY TIME.

I can't find where supermium installs

The best/easiest way to tell is to launch Supermium and load "chrome://version/" in a tab; scroll down a bit and in "Executable path" you'll see where the main executable (chrome.exe) launches from ; one line below, there should be "Profile path" and it just tells you where on your disk Supermium's current profile is located (all default and custom browser settings and associated files) ...

yea as i mentioned it was about probably 30 seconds or more after opening, not immediately the second you would do so.

I use Supermium v122, it worked fine for opening Cloudflare-protected sites until April 2026.
But since May 2026 it can't open Cloudflare-protected sites anymore, it can render the sites perfectly fine but the Cloudflare doorman says: "NO ENTRY
FOR YOUR BROWSER"!

Test page:
https://www.crx4chrome.com/crx/353803/
https://www.crx4chrome.com/go.php?p=353803&i=ncigbofjfbodhkaffojakplpmnleeoee&s=zsYGZ5McvPQqw&l=https%3A%2F%2Ff6.crx4chrome.com%2Fcrx.php%3Fi%3Dncigbofjfbodhkaffojakplpmnleeoee%26v%3D0.1
I try to download v0.1 Crx but I CAN'T download the .crx file hmm, the Cloudflare security verification keeps loading in an endless loop.

Will browser-spoof with UA work for Cloudflare-protected sites? And if YES, any recommended UA strings for me to try?

Edited May 29May 29 by we3fan

I would recommend updating to version 144, that opens Cloudflare sites OK for me.
Incidentally, they are now blocked on 360Chrome too, so I think that's the beginning of the end for any further use of that browser!

No UA will fix that.

crx4chrome may be trying to INSTALL instead of trying to DOWNLOAD and the INSTALL is being blocked (ie, such as would happen if using an UNGOOGLED version).

 

Does v122 have a flag similar to this?  ie, the MIME type options would be to DOWNLOAD instead of INSTALL:

windows offer functions for directorys

often they are sniffed together

they offer like
 

C:\ - (rootdrive)
C:\windir - (aka C:\windows)
the others are then sniffed together

like C:\windows + \spool = C:\windows\spool

%windir%\system32\DllCache = C:\windows\system32\DllCache

 

ExpandEnvironmentStrings is a such core function
a other is SHGetSpecialFolderPathA

https://learn.microsoft.com/en-us/windows/win32/api/processenv/nf-processenv-expandenvironmentstringsa

https://learn.microsoft.com/en-us/windows/win32/api/shlobj_core/nf-shlobj_core-shgetspecialfolderpatha

%ProgramFiles% (probaly like rootdrive (c:\) + (Program Files) = c:\Program Files

%ProgramFiles(x86)% for example is not for x86 its a folder for 64 bit OS
on 32 bit this function fails

%APPDATA% for example is different in XP to win7 but in xp it is C:\Documents and Settings\All Users\Application Data

 

with 

%ProgramFiles%, %APPDATA%,%SystemDrive%,%ALLUSERSPROFILE% and %windir% - you probaly can make all the folders you need

 

also often this strings are often stored somewhere in the registry

Er, are you sure that post is in the right thread?
It appears to be nothing to do with Supermium.

If it's not, I can move it for you.

I think he has the right thread.  Just a language barrier.

He's basically referring to how Cloudflare does *NOT* rely solely on UA.

about that one if its not a event problem, how about a debug version - chrome compiles slow for me like 2 weeks

but advance debug information should show where this come from
