It appears that the issue I had in my WinRAR thread is not specific only to WinRAR. I tried several simple apps including a cracking tutorial sample. This time I tried setting the rFLAGS register after a cmp so the JNE would not branch and I single step the JNE and WinDASM just runs away executing everything until I get an error messagebox. This also sometimes happens if I set the EIP directly. This does not appear to be correct behavior?

I think it has something to do with the trap flag. The flag is 1 and then it goes to zero. I notice i get problems whenever that happens however I can't toggle that flag via w32dasm. anyone help?

Did you tried with OllyDbg ? Maybe it's just because Win32Dasm is a bit old now to handle some traps.

Yes I have came to that conclusion myself. I'm researching several different debuggers including Olliedbg and IDA.
