Hi
I set the registry setting BreakOnDllLoad to 1 to find a problem in the DllMain function of my dll. Like that WineDbg stops first while loading NTDll.dll. After continuing with c it stops again at Kernel32.dll. If I try now to continue with c I get an "illegal instruction in 32-bit code" and I can't continue. Without the registry setting it starts up without a problem. Has anyone else had this problem?
