For some time time I can't always hilite text that I want to copy, that is to say it may take 2-3 tries before hiliting takes place, the cursor is erratic at times(jumps) and in general a big nuisance. Some of you may suggest that I change browsers but I happen to like IE and have always used it most often. Of course, if you tell me there is no hope--then I may consider another browser. Can IE be deleted and re-installed? I am using Windows 7 Home Premium on this Compaq PC. Any response will be appreciated and as usual, TIA.
EDIT: I failed to indicate the browser is 64bit.
