I was debugging something from `emacs -Q', with *scratch* in the top window and `*Backtrace* in the bottom window (no other windows in the frame). I wanted to see more of the rightmost part of *Backtrace*, without scrolling, so I enlarged the frame with the mouse, extending it to the right. At some point the split changed to horizontal, putting the *Backtrace* window at the right instead of the bottom. SURPRISE!?! This of course made things even worse, as the *Backtrace* window was then even narrower than it was before extending the frame to the right. More importantly, I *didn't ask* Emacs to change the window-split direction. This should not happen (by default), IMHO. Sure, I can compensate, e.g. by using `C-x 5 2' or by scrolling. But a user shouldn't have to compensate for Emacs planting obstacles in her way suddenly, out of the blue. Dunno just when this changed, or why, but it seems wrong, to me. Please consider backtracking on such a "DWIM" surprise. I don't care about this problem for myself, as I don't encounter it with my setup. But a priori, and naively, I'd think that this would be bothersome for other users - hence this bug report. If you disagree then just close the bug. Thx.
