This is very interesting. I have done work with Performer and ViewKit with
exactly the same problems with menus. The only solution I have found is not
to draw the Performer scene until some time has passed from widget creation.
For example, if the backround task is not initialized before expose callback
is called *second* time, menus work OK. This is the "solution" I use for now
(I have a splash screen anyway in front of Performer window, so I certainly
get 2 expose events before the user can see Performer window, and everything
kind-of-works) and it seems to work also in Glenn's program. But I don't
think this is a good excuse for everyone to use a splash screen...
Could someone from SGI look at this? Since more than one customer is getting
this behavious, I think it would be worth documenting (or even better,
fixing:)
Regards,
Harri
P.S. I have occassionally had problems with some other widgets that are
created in Rapidapp, but are not visible in my application that uses
Performer.
