For some reason, while editing a block, the Block interface disappeared. So I was not able to push the close/update button.
Not beeing able to exit the block-editing modus, all other geometry in my drawing stayed frozen. So I thought exiting Rhino alltogether and restarting would fix it… Unfortunately, when re-opening this drawing, it starts again in frozen/block editing modus.
Could someone shed a light on this behavior?
Thank you ever so much!
