When saving a document, the progress bar shows on the bottom screen.  When the
save is finished, the regular bottom of the screen returns, but the UI remains
disabled for some period of time after this.

I believe it would look better if the progress bar was released by the routine
that re-enables the UI rather than the progress bar disappearing but the
application in locked out until the UI is enabled.
