I just downloaded TI 8.0 Build 903. Did an update over Build 826. 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. 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. It's a Logitech optical mouse with USB cable. I had this same problem when I upgraded from Build 800 to 826. Have not upgraded since then. Thought the problem might be fixed by now but guess not. Guess I will create "sysinfo.txt" and send it to support.
