I am now running 3.7 with KDE 3.3.2. All my apps seem to be running, usually even better than in 3.6 :-).
I *have* run into a few places where 3.7 apps do not work quite like the 3.6 apps. These are more likely KDE problems than OpenBSD problems, but maybe someone will know how to fix them. xmms - scroll wheel on the mouse no longer adjusts volume. konsole - even though I have a file /home/daf/.kshrc with "set -o vi" in it, every new konsole session ignores it. I have to type 'set -o vi' in every session before that session will allow vi-style command line editing. Investigating the settings for konsole, I find the sessions set as linux consoles with bash. I have so far not figured out how to make the shell - ksh settings 'stick' so that a new shell shows those settings immediately and recognizes the set command in .kshrc. This in spite of saving konsole settings every way I see possible including 'save as default'. I haven't tried everything, but the upgrade process from 3.6 was not as arduous as I anticipated. Nice Work, Developers! Thanks, Dave
