When in doubt experiment.  Intuition does indeed keep locks on windows
for long periods of time like that.  (Although it doesn't in the case
of a slider bar.  That one I hadn't experimented with.)  The drag and
size gadgets both lock the entire window which they are in (an admittedly
reasonable course of action. Although one could unlock periodically for
a moment and sleep, to allow other processes to update their windows.  
Right clicking also locks the front window if pull down menus have been
defined (also for obvious reasons.)  It pleases me to no end that playing
with gadgets does not.  Another thing done right in the O/S.

Maybe I'll get around to writing a program that doesn't steal the entire
machine one of these days.  Not that I don't like the O/S, I just don't
have a whole lot of use for it in my own programs.
