My Screensaver can be installed (by Install option when right-clicked on the file with Explorer) and run correctly for the first time while being in Display Properties Window. I can run it here (Dialog and Preview working) as many times as I want. But when I click Apply and return back to Display Properties, it crashes under WinME with Kernel32.DLL error. It doesn`t even start my application because very first line of WinMain is creation of LOG.TXT and it if would crash inside my application, the error message would state that it`s inside. Just to be sure, I put try-catch handler into WinMain but it doesn`t even get to WinMain. What`s even more weird is, that the screensaver runs itself after specified time (alwyas in XP, less often in WinME where it crashes). However, WinXP doesn`t show this Kernel32.DLL error when being for second time in Display Properties. It just does nothing (but at leat it won`t craash under XP). Any ideas ? VladR www.avenger.sk

Well, I install it after copying into Windows\System folder, so it`s all there. Logging surely can`t create crashes itself. I really don`t know.
