>If you start them separately in Windows they should not be visible to each other. However, (correct me if I am wrong) they will be using the just one instance of runtime library. IF I am not mistaken, I think I have seen something on UT long ago about possible conflicts between two apps even if they run this way. I was not able to find that message, but somebody might remember.
Old FPW2.6 would "share" the same runtime, but I don't believe VFP does.
