This has been bugging me so much, I was hoping the 10.4.1 update would have fixed this, but here it is... In its full glory... My frozen dock... I have my hot corners set up so perfectly, makes me work so much faster, but my dock just stays in its magnified form, and will stay that way unless the mouse goes over it again... So irritating! (NOT every time, but often enough to make me angry) Apple, please make it stop! Does this happen to anyone else?
