In the last three days, my computer has become hyper, and I am not kidding. Everytime I attempt delete of one item the computer goes wild and will delete three or four items adjacent to the one I want to delete. This happens on all pages I use whether home email, gmail or web pages. In addition, when I attempt to place the cursor in another spot, the word near the cursor is highlighted, and, if I do not notice quickly, the word is deleted. Clearly, some problem has developed and I am hoping someone will tell me how to stop it, please? Windows XPpro, SP3, Word 7 (I note that due to other problems that have occurred since installation of Word 7). MacAfee is running a full system scan as I write. I used Optimizer 3 yesterday. I appreciate advice about dealing with my suddenly hyperactive computer. TIA Rick
