I have had this problem for years - it caused me to stop using desktopX years ago, but now I have XP loaded and tried using msstyles, thinking it might be more stable - That's what I get for thinking...
Years ago, when XP was new, I used desktopX on a variety of PC's, using AMD and Intel processors, with both Win2K and XP, and the problem was identical on all platforms. Every few minutes, when opening or manipulating folders, or when using the Start menu, the screen would lock up, then eventually give an error that explorer.exe had caused errors and needed to restart. It would then restart explorer, and all would be back to normal (except that all of my open folders would be closed). I finally stopped using OD, and the problem stopped.
Recently, my home system and my work system have both been upgraded to XP (still not sure if that's an upgrade!) - XP Home on my work computer, and XP Pro on my home PC. Started using msstyles, and the problem is back.
My home PC is the same one I used OD on years ago (AMD Athlon 750MHz), but the work PC (Pentium 4 1.8GHz) is a new one that I haven't tried to skin, until now. Both have the same identical problem as the ones I used with OD - It seems that any time I try to change the window style, explorer crashes every hour or so - no matter what processor or OS I use. Again, this happens with multiple different PC's with different processors, with XP Home, XP Pro, and Win2K.
I've searched this forum for posts pertaining to this, but none of them address problems with msstyles (though I suspect it's a problem with multiple, maybe all skinning apps).
Has anyone else had this much trouble?
