We've decided to remove all "update" commands from our Tk app, as they routinely hang our ap
p.

Iwidgets has many embedded uses of update, which also lead to update hangs:

"C:\Tcl\lib\iwidgets4.0.2\scripts\shell.itk"(250,5):    update idletasks

"C:\Tcl\lib\iwidgets4.0.2\scripts\scrolledwidget.itk"(373,5):    update idletasks


Short of fixing all this, I don't see any alternative to pulling out all our Iwidgets -- a m
ajor pita.

Any suggestions?
