Hahahaha. Thanks.
Actually I LOVE my Intellimouse and have been using nothing else for years. I am on my 7th Intellimouse, not that they fail often, just that I use them a lot, and sometimes in gaming the use is intense.
I find it rather odd that the mouse still works (and all the buttons) without that driver... (except maybe the left/right scroll with the wheel, which I never use anyway).

By the way, Xara Support has been in contact with me frequently and almost immediately since I first sent in a support ticket. They were most helpful, but I contacted TG first and hence the answer came from here, first. Thank you, Xara Support, also.
