Help with pop-up menu/choice button, please.

[Martin Baxter]

Alex,

Not clear whether you are using the popup command already, but if not, 
that might help. Using this you can test whatever you want before 
issuing the command that invokes the popup, something like (in a regular 
mouseup button, locked field etc.) :

if [condition_false] then
     exit to top
end if
popup btn "mypopupbutton" of cd 1 of stack "bla_bla_bla"
## I then routinely add:
if "Win32" is in the platform then then
     wait until the mouse is up with messages
end if
## because on windows the popup command may not pause the script

## the menupick handler itself goes in the popup btn not here
