What I have noticed is that sometimes when I try select a running application from my KDE panel via mouse the switch does not happen. Switching in these cases will usually work via Alt-Tab however. The program being switched to seems to be functional. Maybe this is just a problem with kpanel. Like I said, I'm out of my depth here. To recover I usually end-up killing the process I tried to switch too. Even though I quite literally spend fourteen to sixteen hours per day with my FreeBSD system there is only so much a person can learn in a given period of time. This is one of those issues that for now I have simply shrugged, adjusted, and carried on with what I was doing. Here are my system details FreeBSD dwpc.dwlabs.ca 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #1: Fri Mar 24 19:34:58 AST 2006 root@dwpc.dwlabs.ca:/usr/obj/usr/src/sys/DWPC-200603230410 i386 3:41AM up 1 day, 5:48, 3 users, load averages: 0.03, 0.10, 0.08 X11R6 XOrg 6.9.0, KDE 3.5 I have noticed this in 6.0-RELEASE as well I hope this is at least in some way useful. Maybe it is not even related. Other than this I have nothing more to add except that if anyone has any ideas maybe I could help test them out. --Duane
