NO! If you do that then it's not COM! Put extern(Windows)! It's 
the only way it can work!

Yes! your right, If you were only around to tell me that in the 
first place! ;) Now we know. Again, as I said before, the problem 
is informational. Maybe because come works 99% of the time 
doesn't help us in the 1% if some think 99%=100%(that new math 
shit that's causing so many problems). I've created a big enough 
stink about it that anyone in the future having similar issues 
might be able to resolve them much quicker.

Thanks.
