On my sons windows XP desktop the cursor wont stay on task, if you click a typing box it goes away after a couple seconds on it own. Or if you try to use drop/windows menu it goes away after a second or two. Does it in all programs and all applications. It only does it on "limited accounts", but if you are logged into a "administrator account" at the same time it does not do it, ONLY IF the "limited account" is logged in by itself it does. I tried a different mouse and key board and i tried to delete his accout and create a new one and nothing helped. And he tells me after a hour or more it eventually will quit doing it. So right now to make it work for him i have to login to the admin account, hit switch users and login to his account. in other words both accounts have to loged in. p.s...when i switched his account to a admin acct, it did not do it. but that isnt a perminate option.
