Hi Craig,

Just another thing I could see:

Crystal 9 doesn't list my dll but I get the "file access denied" when trying to re-compile my DLL.
If I close Crystal, I can compile without problems in VFP , it means that Crystal is loading my dll but I can't see it.

Just to tell you. Maybe it can explain something.

Thanks.
