Subject: 23.0.60; windmove.el doesnt not always switch windows in ERC
Date: Sat, 9 Aug 2008 12:39:51 +0200

Hey,
 I don't have window-move.el, it's defined in windmove.el
 Also, when i was debugging i had the ERC buffer running in the bottom
left corner.

When I run debug on windmove-find-other-window it doesnt give me any
output, but does take me to line 468 in windmove.el. The line is
(let* ((actual-current-window (or window (selected-window))) in the
function windmove-find-other-window

If i do the debug on windmove-right, nothing happens

I may be doing something wrong because I have never debugged lisp code
before, so could be doing it totally wrong. I am a programmer though
in C++, haskell, python and java though, so I do understand the
concepts behind debugging lisp. I'll read the info pages on edebug
sometime so I can maybe investigate the problem as well.
