I think you were hit by some incompatibility between additional emacs packages and the emacs version. Do you have any external elisp files? If not, did you run emacs-updater? In fact, I got some backtraces and errors until I ran emacs-updater, after that, almost every package worked correctly, except for an external one that needs to be updated due to some changes in the way font-lock is done. Anyway, that was probably what made me postpone the upgrade: too much work, fixing old packages by hand *and* figuring out which other settings did they change. (If you end up trying emacs-updater to fix emacs 24, you will need to run it again after eselecting emacs 23, if you want to go back to emacs 23.) >> they really changed some of the defaults... it seems, for example, >> that Emacs is not doing copy-paste as expected anymore (tries to rely >> solely on the "clipboard", ignoring the X selection), > > I hadn't noticed that one, but 24 was so unstable for me that I didn't > use it for very long before I went back to 23. I've noticed this one, because I sometimes rely on copy-paste a lot. And by copy-paste I mean the X selection... >> and now highlights regions by default, like if setting the >> region was like doing text selection in a program such as Notepad.EXE. > > I have that enabled in my .emacs file anyway. This kinda distracts me, I've got it set in a way that, if I hit C-space once, it does not highlight. If I, for some reason, actually need highlighting, I can hit C-space twice. >> As some day I will have to switch to 24, does anyone have a list of >> settings to revert to the old Emacs behavior?
