i just purchased the MacAddict Mac Handbook which has a bunch of programs on disc. i installed Dockextender and it totally messed up my computer account. first of all my dock disappeared and i cant get it back. if i go to the dock preferences and change the settings it always reverts back to 'position on screen bottom'. also when i try logging on AOL, it always freezes. on top of that everything seems to be running much slower. This is on my main admin account. everything seems to be fine on my other accounts which is what i am on right now. any help would be much appreciated.
