Did you update your drivers - or just disable Hardware Acceleration?
Disabling hardware acceleration is not a fix - it makes for terrible performance. It's just a test to workout if there is a driver issue.

i just disabled the hardware acceleration.. i just needed to finish my model quickly.
So.. Does that means ill have to update my drivers ?
My card is a Nvidia Geforce GT 2Go

Works Again ! Thank you so much !

Hello everyone! I'm kinda new here
I hope someone could help me, I have a recurring problem with Sketchup8 (I work with windows7).
Well, the point is that: after a few minutes modeling, my cursor starts going crazy. It leaves traces and all modeling commands (pencil, square, mesures, etc.) lock. However, I still can save my file, but it happens so often that I can not move forward.

Thank you in advance!
