add menu-background vanishes

[Rich Lague]

I have an intermittent problem with the menu builder:

When I go to create a menu bar, on a stack that does not yet have one, 
my card background (and all the controls on it), disappears. I have not 
been able to figure out how to get it back. I end up 'reverting to 
saved'. It doesn't seem to happen to all stacks.

The cards go blank the second I click OK to create a new menu.

Anyone know what's going on?

Thanks,

Rich Lague
