Specifically, it shows the stack. When an application is built with Debugging Symbols, it means that it has 'identifiers' and 'names' inside it to help people debugging (seeing what's going on). You can see (part) of that in a sample of your backtrace: > =>1 0x7e8789cf ICSeqCompressFrameStart+0xff() in msvfw32 As you can see, that part of the backtrace has useful information (the name of a function, in this case: ICSeqCompressFrameStart). It has this info because Wine was compiled with it enabled. If you could find a version of HyCam2.exe with debugging symbols (which I doubt the author provides, but you never know) it would be useful for others to understand what is going on inside your application. However, it would probably be more useful to get a version of Wine with more debugging info. Cheers, Jorl17
