Forums Scripts & Popups dll problem

I've wrote a dll in Delphi 5. It's working fine, but only when the class i've implemented is in the same unit than the procedures und functions I use. If I try to include the unit, I can compile and build the dll, but when I start the dll out of mIRC, it crashs. I've also wrote the dll for normal use and it works fine with the 2 units (1 for the procedures/functions, 1 for the class). Has someone an idea, why this could happen? Can't understand, why this isn't working...

I'm no expert in Delphi, but did you make sure the symbols were exported so mIRC could find the functions inside the DLL. Other than that, maybe post the simplest crashing code could help us see if a potential problem arises.

It's pretty easy to crash mIRC with bad pointers and such stuff.
