Can you try creating a shortcut, and setting its icon to the hippo in each of these two DLLs? The _vista one has the hippo with all resolutions including 256x256 png, and the _xp one has the hippo with everything but that. On both machines--XP SP1 and XP SP2--these shortcuts seem well behaved. Their icons are hippos in windows explorer. They remained hippos when I copied both shortcuts to each machine's desktop. No crash was observed with the dll as the source of the icons. Just for yucks, I tried dropping both resource dlls on the 1997 borland C++ 5.02 IDE, which is designed to extract resources from executable binaries. The 'xp' dll loaded fine: I could see all the icons, and even manipulate the hippo. The 'vista' dll failed to load, giving a messagebox: Resource compiler error: Invalid icon format I also tried dragging and dropping the 'vista' dll on my 2004 copy of 'irfanview'; it correctly displayed the classic 32x32x24bpp Cygwin icon. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

A BSOD can be caused by any faulty driver, application, or service in the system. It can also be caused by faulty hardware. Bad ram will cause memory corruption and make programs or drivers fail to run properly. I have diagnosed BSOD errors before and tracked them down to both faulty ram and faulty hard drives.

Enable full crash dumps in the system preferences, install windbg, trigger the crash, then (after rebooting) open memory.dmp in windbg; the output of analyze -v should tell you at once which driver was on top of the stack and so should be suspected. If you're lucky, you'll see the driver name on the BSoD and won't have to go to such lengths, but if it's a level or two up the stack when the crash happens, you'll need a debugger to show you the relevant module name. cheers, DaveK -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Well, *any* BSOD is by definition a bug inside ring 0 (e.g. the core Windows kernel, or a graphics driver. So, it isn't *.ico's fault. Yes, apparently it's an XP SP1 kernel defect: in 'win32.sys', PAGE_FAULT_IN_NONPAGED_AREA, STOP 0x0050. I also tried the original .ico on an XP SP2 machine, which produced a different BSOD. That machine was set to reboot itself upon BSOD, so I didn't have time to record the message; but the program name began with 'ati', so it was almost certainly a graphics driver. But those are defects in ring-zero programs, so it's their job to avoid crashing no matter what .ico file is handed to them. The resulting vulnerability is their fault--not the .ico's fault. BTW, both these machines have no known hardware problems, and recent full runs of memtest86 indicate that their RAM is fine. Still, it'd be good to avoid...

Hmmm. Well, the .ico contains the *vista*-approved sizes: Okay, yet many large-corporation IT departments are sticking with XP for the foreseeable future, even for brand-new machines. And apparently the vista-sized icons aren't gracefully ignored by XP (SP1 at least), no matter what ms may say. BTW, the graphics drivers on the SP2 machine were current when I checked them for updates about two weeks ago. Supposedly, the 256x256 png-compressed size should be ignored on platforms that do not support it -- but maybe that's causing your problem. Try the attached version, which omits the 256x256 resolution. This new .ico works fine in every graphics program I can find, even on the XP SP1 machine--specifically including the two programs that failed with the original icon. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
