Issue 2 KX: 4.0.12 (RC2) - no problem with earlier versions Many times when starting Windows, the wallpaper will appear and then nothing. The mouse cursor moves but no other activity. Pressing Ctrl-Alt-Del once does nothing, twice shows a "Windows is busy" blue screen. Pressing a key, gives the Task Manager. Task Manager shows only one process - mprexe (not responding). After I end this task, there is some disk activity then nothing again. Then Ctrl-Alt-Del again as above, but this time it shows msgsrv32 (not responding). After ending this task, nothing - I have to restart. Workaround: Install Revolutions Pack 9 (with KernelEx 4.0 RC2) (!) I think that kernelEx 4.0, by default, when install, sets all software to use it's extensions, is pretty risky, and unessisary. I think I only need to enable kernelEx when the program is not compatible, most software on my system are already running well without kernelEx or they wouldn't be there in the first place. I have found many programs which work in pure win98se will crash or produce error when enabling kernelEx, so it could cause system not to boot properly after installing kernelex, and people would not know what hit them. .
