problems with popups

[Terry Judd]

  I seem to be having a hard time getting popup menus to to 'stick' open 
under Windows. I'm using a 'rectangle' type button to popup the 'popup' 
type button (popup btn "historyMenu" at the bottomLeft of me) and the 
following happens (auto hilite of 'rectangle' button is true) on 
mouseDown

1. 'rectangle' button hilites
2. popup menu displays, and continues to display while the mouse is 
down but a mouseUp message is sent to the 'rectangle' button as soon as 
the popup displays

and on mouseUp...

3. the 'rectangle' button's hilite stays on or off depending on its 
initial state when it was clicked

I've been able to fix the hiliting problem by checking the state of the 
mouse in a mouseUp handler and sending messages to it until it is up 
and then setting the hilite correctly. However, to get the popup menu 
to 'stick' open I have to put a "wait until the mouse is up with 
messages" line in the mouseDown handler - before popping up the menu - 
but then (of course) it doesn't appear while the mouse is down. This 
stuff seems to behave correctly under OSX.

Has anyone experienced these problems and if so can they suggest any 
solutions/workarounds.

Cheers,

Terry...

BTW  I can't get menus displayed using "popup stack [stackName]" to 
'stick' on either OSX or Windows.
