ATI Mobility X1400 -Graphic problem

[blacksimos]

Hi!

I have got a serious graphic problem with Dungeon Siege II (+ Broken World). I tried to play this game in my laptop (Acer Aspire 5672WLMi, IntelCore Cuo 1.66, ATI Mobility X1400 256MB uptp 512 MB). The problem is that when I move the cursor at the menu screen or in-game screen, there is only a small square around the cursor with graphics (the rest of the screen shows nothing!). Of course when I don't move the cursor, everything is perfect!

My video card drivers are quite old, because ACER does not update its video card drivers and ATI Catalyst cannot be installed (ATI says that ACER laptops aren't at the supporting drivers list).

Any ideas??? Thanx in advance
