I just downloaded TI 8.0 Build 826. Did an update over Build 800. Created a Bootable Rescue CD. Booted from the Rescue CD like always. It did boot up fine but no MOUSE. I could move the cursor between the 4 options on the main screen but couldn't do anything else. No way to shutdown TI, even the power down button on the tower wouldn't work. Had to turn off power on the surge protector. Created another Rescue CD using TI 8.0 build 826 with same results. I then inserted the Rescue CD for build 800, booted, mouse works fine. This is a bummer. Win XP Home SP2 on a Dell 4300. Mouse is USB 1.0 plugged right into the USB port on the tower like it has been for 3 1/2 years. This is first mouse problem since I purchased the software last fall. Am I the only one with this problem?
