Installation process freezes without muose input

Hi, I have a problem with installation of openSUSE 11.2 and other linux distrutions on my notebook… during the installation process, this process freezes if I don’t move the mouse or press any key for a few seconds… but, when I move the mouse again, the process resume for few more seconds…
Can anyone tell me if this problem is known and how to resolve it?
Thanks for answers :slight_smile:
