Stuck in an Enter a Number Loop

Help! Is there any way to break this loop? I can’t enter a number because the “enter a number” warning keeps popping. It started because I hit the spacebar instead of a number accidentally. The escape key also won’t break me out of it. I had not saved in awhile, otherwise I would end the process willingly.

if you press ok on the pop up does it show automatically again? if not and you get the chance to write something at all maybe ctrl A to mark the field then enter a number, just a blind suggestion though.

Oh well, nothing was breaking the popping warning out of its loop so I wound up forcing Rhino to close and redid the work. The behavior doesn’t repeat for me now so I guess it was a one-off.
