Frontscript to simulate modal dialog

I've done that, and it works some of the time, but not all the time.  I 
may have to add a timer to check that the progress window has actually 
been brought forward after 1 second or so.

I'd thought of the transparent button, but not using it in conjunction 
with a palette because I'd assumed that the palette would have a 
palette-like border.  But I'll try that, thanks.

By the way, I'm surprised that this frontscript doesn't actually trap 
any mouseDown's, is anyone else surprised?

on mouseDown
   put the rect of window "Thumbnail Progress" into theRect -- this is 
the progress dialog window
   put the screenMouseLoc into theLoc
   if theLoc is within theRect then
     pass mouseDown
   else
     beep
   end if
end mouseDown

Best,
