Hello again: I went to a Windows help site and found a great many people share my problem. I read many potential solutions offered by numerous users. And it seems that the problem comes down to the subject of your last post - the touchpad. One user referred to a program called "TouchFreeze" which disables the touchpad when typing. All those who installed it had positive results. So I decided to give it a try. So far I am optimistic. I typed about ten lines without the cursor jumping once. I'd call that definite progress! At least we know now it wasn't caused by a virus. Isn't it ironic that you came up with the problem almost at the same time I found it on the Windows help site? But I'm giving you credit for the find since you went through all the trouble of starting from the ground up. And I can certainly say I have the cleanest computer in town :-) Thanks so much for all your patient help. And please - Have a whole six-pack on me! Sincerely, Jeanmarie50
