Wireless Optical Mouse messes up screen

Hello, I am using Suse 9.1 Pro with kernel 2.6.5 on a dual boot Toshiba Laptop. Today, I tried a Microsoft Wireless Optical Mouse for the first time, and I installed the accompanying CD on the Windows partition. Then, I booted the Suse partition, with the receiver connected to a USB port and hoped that Suse would detect the device. Instead, my login screen is completely messed up, and the mouse icon is like a large square. I have to switch to tty1 to shutdown. How should I proceed to restore my login screen? How can I get this mouse to work on Suse? John
