The problem is that switching focus between windows (frames) does not
update which window is "live". The most-recently created, or
most-recently resized, window is always the live one. If I switch focus
to one of the other frames, it doesn't update, and I need to move it
around somehow in order to make it live. Then the other frames go dead.

Before the breakage, it's possible that the non-visible frames were not
updated while they remained invisible, and I simply never knew because
I couldn't see them. Now they stay un-updated until I manipulate the
size of the window somehow.
