Crash when debugging

WarRock crashes when I attach a debugger (like in "See what writes to this address"). Is this normal or do I something wrong?

Thanks in advance,

Koekenbakker.

IsDebuggerPresent();

I'm new in searching addresses and using (U)CE. So could you explain what you mean with that?

Thanks in advance!

Btw, WarRock crashes with several UCE's and also with CE..
