Fabio,

I found it. I went through the entire project once more and two class-programs made me suspicious.
Although they were in seperate prg's they both said the following:
DEFINE CLASS import_Access AS Session OLEPUBLIC

I changed one of them and the problem went away.
Thanks for you input.

I still think though the VFP should return a better message than the one it shows now....

Regards,

Ron
