cannot deletenodes/undo bug

I've discovered a way to prevent yourself from being able to delete nodes with the delete key or ctrl+z to undo (on windows 10,RHINO 5 SR12 GH 0.9.0076).

if you open a grasshopper window (non full screen) and double click the bar at the top (which would typically full screen a window), it becomes a super teeny tiny thin 'bar only' window.

now, maximize it while its in this state (by pressing the maximize button), or resize it so you can see the content. if you try to interact with nodes it will let you do so via the mouse, but if you try and delete a node or undo (potentially any other key command), nothing happens, and it does it in the rhino workspace.
