Hi I've had some crashes and freezing problems on my iBook G4 1.33Ghz 40GHD 512Mram The problem normally happens after or while I'm downloading something (software updates or plain software) with my dial up conection... The Dock freezes & the widgets tend to be sloooooooow or never launched or it takes them several I mean several minutes to work (I only have 7 widgets that I use, and 4 of them are worldclock) Anywhay I've searched the forums and found several answers about similar issues that recommend to delete from user preferences the following; com.apple.dock.plist What I want to know is what are the effects, and what do I need to do afterwards...? a Restart will be fine and enough? BTW when it crashes everything freezes... internet conection works, itunes play but I can't get to shut down or restart the computer without the powersource button... Ohh and the other day I got a Panic automatic shutdown... WTF is that???
