In short, the software/drivers for the touchpad on your laptop did not load properly. It may have been a one-time glitch in which case there's nothing to worry about. However, if it continues happening you'll want to reinstall the software and drivers for it using your recovery CD. If you don't have the CD or cannot find the files, you should be able to download the latest version from Toshiba's website.

Hope this helps,
