>I'm trying to convert a VFP 3.0 app to VFP 5.0a. When I try to generate a menu, the whole VFP session is blown away. I made a new menu with only one item, generated it and the same happened. Then I tried a "quick menu" with no changes, generated it, and the session was blown away again. I haven't found anything in help or at Microsofts site (yet); does anyone have any idea what I'm doing wrong?

Are you saying that a simple menu created in 5.0 and generated in 5.0 crashes VFP?
If so, I would vunture to guess that you need to recopy genmenu.prg from the cd.
