I'd think something like putting a boolean method like "movingBack()" or 
"previousPressed()" in IzPanel that always returns true when you can move 
back, so it can be overridden in a Panel class would help.  I know you can 
lock the Prev button, but this would be different.  For instance, with what 
I'm working on, this would give me a chance to take care of a few things 
before the previous panel came up.
