Magic Trackpad Lag
Recently, I'm having a problem when I am using my Magic Trackpad that whole OS becomes laggy. My Magic Mouse does function very well. However, when I just move the cursor with the trackpad, everything becomes slower. For instance, when I point finder icon with my trackpad, the text "Finder" appears after a second or two.
This is very uncomfortable for me to use the trackpad. Is there any way to fix this? Or anyone having same problem with me?
