If your Logitech mouse is running fine in other programs, but very slowly in SketchUp, there is a setting you can switch to eliminate this problem.
The newer Logitech mouse drivers have a special setting for use with games that disables acceleration, but this actually applies to all applications that use OpenGL, which includes SketchUp. To re-enable acceleration:
- Open the "Properties" dialog box for your Logitech mouse driver.
- Click the "Motion" tab.
- Clear the "Disable acceleration in games" check box.
