I have been using a Logitech Ultrathin T630 mouse with my SP2 for a month or so now and have found it far superior to the Microsoft Arc Touch mouse I had been using earlier. The only problem that I find a bit aggravating with it, is the fact that, for some reason, while surfing the web or whatever, it wants to cause the SP2 to jump back to my desktop. I realize that tapping the T630 takes you back to the desktop and I really don't think I'm doing this inadvertently. Has anyone other than myself that might be using this mouse observed this? I've posted this question on the Logitech forum, but I get the same lame answer: "Our Logitech Ultrathin Touch Mouse T630 was designed to be used with computers only and that might be the reason is not working properly with your tablet. Kind Regards, LillyG09 Support Specialist"......How much of a "Support Specialist" do you think this person is??
