>I'm not sure about VFP, but in 2.6 you won't have an error when you call a function in the other APP and this one is no longer in the memory. The call is just ignored. This is extremly tricky. What's even more weird: the APP goes out from memory if you delete or move the APP file on disk! Not really weird if we think a little... :)

I'll try the delete trick and see how it goes. Thanks.
