When using grasshopper inside Revit I often lose the ability to make keyboard inputs, ie: copy, paste, delete, etc.
It seems to jump between Rhino, Revit and Grasshopper randomly. Even when I make sure that the grasshopper window is active, it still stops working. The only way to correct is to close all three programs and reopen. It only lasts a couple minutes before the problem arises again.
Any ideas what might be the cause of the issue or how to fix?
