Hi Mark.

I think the problem is the version of VFP. I was trying to use VFP 5 and the problem appeared.

I've made the same test using VFP 7 and this problem has solved. Another appear! :) I have to call a DLL and VFP returns "DLL could not be loaded" or something like this... (I don't have the right message here)...

I'll test KONxiSE to see which is better for me! ;-)

Thanks for your help!
