I deleted Konfabulator from my 15" PB (which runs Panther 10.3.9) as one of their widget (world map which shows daylight and night areas) did not get off my desktop (I clicked desktop in the preference for that widget by mistake). I deleted that widget first while Kanfabulator was running. I ran repair desk and rebooted as well. Then, my Panther behaved strangely, such as: 1. dock became very slow to pop up (my dock is set "hide" when not used). 2. dock's magnification did not work 3. pull down from the menu bar at the top of the screen automatically runs from the top item to bottom item (ie. new window, new tab, open file, and etc) even though I wanted to pick one item in the pull down menu. So, I put the plist for dock out of the preference in Libaray and put it back in there. Then, I logged out and logged in again. It seems this fixed the problem. Does anyone know how this was fixed by what I did?
