Unable to use RhinoGet Commands when running through Rhino.Inside Revit

I have a custom Grasshopper plugin that uses the Rhino.Input.RhinoGet.GetPoint() command, and when it executes with Rhino running through Rhino.Inside Revit, the system hangs, and I am unable to make a selection in the Rhino window.

Please let me know if this is a known bug with the system, or if there is a workaround.

Thanks!
