I have a large assembly and when I tried to modify a sketch I could see a bug.
Here is a description of the steps I follow to reproduce the bug:
I open the sketch to be modified. I select a point of the sketch and then I drag it. The sketch disapears but I still can see the point I'm draging.
I have to zoom in or out to refresh the sketch.
I use SW 2009 sp4 with an nvidia geforce 8600 gp. I just installed the latest graphics card driver from nvidia web site but the bug is still there.
Did anyone have this issue before?
