Hi all, in case you always wanted to know where to find a proper Windows kernel debugger: Go to ftpsearch.lycos.com and search for "iwindbg.exe". That's the Windows Platform SDK debugger. Then just add [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug] # command line to start a debugger when an exception occurs "Debugger"="c:\your_path_to_windbg\bin\windbg -p %ld -e %ld" in Windows and you're set. That way you can either debug crashes on Windows or debug programs by invoking windbg directly. That's especially helpful for direct 1:1 comparison of Windows vs. Wine :-) A (crashing) test program to test whether postmortem debugging works can be found at http://home.germany.net/100-30936/download/win32.exe Nice debugging ! :-) (not sure about any licensing issues, though !)
