Grasshopper Keyboard Input Spotty

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?

This should be fixed with the last merge I did in the branch autodesk/revit/wip .
Could you please test it and tell me if works in your computer?

I’ve tested this in several Revit versions and all I can tell you by now is that it behaves differently on each version.

Those are the keys that fail:

Revit Rhino Grasshopper
2017 Del :heavy_check_mark:
2018 (Untested) (Untested)
2019 Del Del, Copy, Paste, F5
2020 Del :heavy_check_mark:

I will continue looking into this.
