Hi Yiy,

This is a quite common video driver issue (I guess your card itself is okay since it used to work with XP). Try this test: go to Window > Preferences > OpenGL settings and disable hardware acceleration. If it seems to solve the issue, try to update your video driver instead of using SU with this, disabled setting since it can slow SU down with larger models.

Hi Gaieus

thanks very much.
problem solved!! however, i didn't quite get you said about updating vedio card part....

Hi guys!

My sketchup problem is shown on the image below.
since I upgraded my laptop from XP to Vista. sketchup has never worked properly on my laptop.

when we draw a line, we select a start point then dragging the line to the end point we want.
here's the problem, wherever the cursor goes, a series lines and dots come out and hardly be controlled at all. Does anyone have the same problem as well? how did you sort it out??

Many thanks
