Lately, when I scroll in Microsoft Word on my MBP, the spinning color wheel will come up with a lag in the scrolling. Also when typing the color wheel with show up with a lag. Its getting more and more frequent. Do I need to reinstall MS Office? How would I go about doing that exactly? I was working in a document with a small picture in it, but should that really make a difference? Everytime the color wheel comes up it scares me becaue I JUST had my internal HDD replaced under warranty because of the "spinning wheel of death" and of course the HDD clicking sound. So really, I just installed MS Office 2004 on this new HDD about 3 weeks ago, so its a fairly new install. I have been having some strange scratch noises coming from the base of the MBP, so Im all confused as to what to do. I still have 3 months of factory warranty left. So....anybody know why this could be happening or some things I should be checking? Thanks!!!
