add menu and controls vanish?

[Rich Lague]

I have one particular stack project that behaves strangely. It is a 
simple membership directory with data about the members in a bunch of 
different fields.

When I try to add a menu all my buttons and fields vanish when I say OK 
to creating a new menu in the Menu Builder. After that I am not able to 
make the content of my cards visible again. The back ground group's 
Visible property is checked.

?? What am I doing wrong?


Thanks,
