I've posted previously that my selection rectangle (whether it's blue or green) would cancel out (previous post). We've found that it is caused by an add-in LevelSet - by Richard Stima.
Simplest solution would be to uninstall the add-in, but it's a great help for us.
We've noticed that if the DWG-file gets heavier, the doubleclicking of the selection window would occur more often.
The developer of the add-in isn't responding, so I'm wondering if someone here could help me with finding the cause of this laggy cursor. Can I modify an add-in from the autodesk app store? And if it's possible, how do I start in finding the cause of the unwanted double clicking of the cursor / laggy behavior.
