After upgrading to Civil 3D 2008 last month, I am having a problem with the cursor getting slowed up while working in the drawing area of both model space and paper space. I have disabled all hardware acceleration, turned off “selectionpreview” system variable, checked the snapmode setting, and rebooted. The cursor works fine in any other program and even within any dialog box while working in AutoCAD. The problem is occurring in any drawing and I even went back to C3D 2007 and the problem goes away in the exact same drawings. Anyone have any ideas on this? Thanks
