IE 7: Missing Keystrokes

[uiplanner]

When I am typing using Internet Explorer 7 (Version 7.0.5730.11), some keystrokes are not registered and don't show up - this happens when I'm typing in a form, an input box or entering a URL address. Typically it's about 1 of every 15 keystokes, but it's definitely variable. If I am very deliberate and slow down my typing, it's not a problem. A likely related issue is that my text cursor blinks in an erradic manner in IE 7. This is not a problem in non-IE applications (Word, Excel, etc.) I have run Spybot and Adware checking for malware, and found nothing.

If it matters, I'm running XP Media Center.

Any thoughts? Thanks in advance.

As silly as it sounds, can you reproduce this issue in safe mode w/ networking?

Man can you please say why you think that would help? i dont know anything about safe mode with networking.

I actually had this same problem happen the other day. Another symptom I had was https was not working. I got mine working by re registering some dlls

start/run

cmd

cd %systemroot%\system32

regsvr32 softpub.dll

regsvr32 wintrust.dll

regsvr32 initpki.dll

regsvr32 dssenh.dll

regsvr32 rsaenh.dll

regsvr32 gpkcsp.dll

regsvr32 sccbase.dll

regsvr32 slbcsp.dll

regsvr32 cryptdlg.dll

When I ran them, 2 dll gave me errors

That is a silly question BUT, the problem does not happen in safe mode with networking. What's that mean? FYI - I use the free security software offered by my ISP (Cox High Speed).

I am not currently having any issues with https (other than the keystrokes randomly not registering in https as wel). I did successfully update the dlls (no errors), but it did not change my problem.

Thanks for the input!

If it happens in regular boot but not in safe mode, then it's either an explorer.exe shell extension, a startup item, or a driver causing this issue (none of those things load in safe mode). You can disable all non-Microsoft shell extensions with ShellExView, disable all non-Microsoft startup items with Autoruns, but as for drivers, you have to determine which applications that have drivers you want to uninstall (antivirus, antispyware, backup, firewall, and most security packages all load kernel-mode filter drivers). Note that disabling these applications doesn't remove their kernel-mode filter driver, only uninstallation.

If it works in safe mode as expected, one of those three things are the culprit (or perhaps a combination).

OK, blast from the past on this one, but I thought I'd follow up in case anyone else ran into this problem. I seem to have addressed the problem by running Sysinternals Autoruns and Googling all the different files that popped up. I found a couple of files published by Data Encryption Systems that I turned off:

1) DNHelper32.exe

2) Dk2drv.sys

The DNHelper32.exe was identified as a trojan or virus / spyware at several sites I found.

Thanks for the help.
