================================================================
Dear Bug Team!

This is one that's been bugging me for years, over multiple versions
of xemacs. If you cancel the mini buffer with C-g, it reverts the
layout of the rest of the buffers to the state they were in when the
mini buffer was originally displayed.

For example, say you have a split screen layout with two files open
that you are editing. You then hit C-x f to open a new file. However,
for whatever reason, you decide not to do that and you continue
editing without using C-g to cancel. You open up some new files,
change the layout perhaps add a 3rd pane, and all the while the file
open prompt is still in the mini-buffer. You eventually notice that
it's down there, focus on the mini-buffer and C-g to cancel. Bam!
Layout is back to the split screen viewing the same two files (and the
positions you were viewing) that you were looking at when you hi C-x f
in the first place, regardless of what you did in the mean time.

The problem is not unique to C-x f, that was only an example. It
happens with anything that shows mini-buffer prompts, such as
searching or M-x. It's pretty disorienting; over the years it's become
second nature for me, when I notice I left a mini-buffer prompt
unanswered, to continue working until I get to a good stopping point
before using C-g to cancel whatever old prompt I left there --
otherwise it's very disorienting.
