Hmmm, I've found that when doing something like a "stop" button, I
basically bypass XMANAGER, and simply poll events for that button
using WIDGET_EVENT() at a convenient point in the computation loop. I
am able to receive events for the "stop" button even if other buttons
have been clicked first. Those other clicks will be ignored until the
computation is finished and XMANAGER is able do deliver them again.

But your points about hourglass cursors and disabling buttons is
certainly appropriate.
