When renaming pretty much anything, the keyboard arrow keys don't move the cursor. This means you need to position the cursor with the mouse. Because the names are small on the screen, you don't always get the cursor where you want it first time....bit frustrating

Regarding the first point, we have seen this intermittently. We are still looking for a pattern or consistently reproducible use case to help us debug it. If you have a lesson where this problem always occurs, please attach the SB4 to a ticket. Thanks!
