Hi Kathleen,

If you can get away with using a menu bar rather than a droplist, it
makes desensitizing subwidgets a whole lot easier.

Something like this:

TLB = Widget_Base(/Col, MBAR = MBAR)
File = Widget_Button(MBAR, Value = 'File')
Frog = Widget_Button(File, Value = 'Frog')
Womble = Widget_Button(File, Value = 'Womble', $
Sensitive = 0)
Cabbage = Widget_Button(File, Value = 'Cabbage')

If you've got over 50 widgets, it might require a whole lot of
rewriting in your case, though. Plus, you can't control where in the
widget your menu bars appear.

There's also the option of using CW_PDMENU which I haven't really
delved into myself, but my experience with IDL functions that begin
with 'CW_' leads me to believe that a *lot* of headaches might lie
down that path...

Best of luck!
Chris
