Ok, I think I understand that, in this case though, the Stack in 
question *is* a main stack, does this make a difference?

The reason I asked is because I have some Stacks that have multiple 
cards formed into a Tabbed Button, one card for each tab, and on the 
stacks that have this control I send a menuPick command to the Tab to 
select the correct card. I was wondering if this would cause 
problems, seems not? Just add it to the fist card of the Stack.

Ok, I will give this a try and report back.

Thanks a lot for your help, you don't know how much I appreciate it. 
Some of this stuff is a complete mystery. The documentation seems so 
scattered that it's hard to know what is going on sometimes.

I guess it doesn't help that the IDE gets hosed so often when trying 
to setup this kind of stuff.

All the Best
