Can people please try this, just so that we can see if this is a bug or not: 1) Remove AirDrop from the sidebar. 2) Set their view as column in the window (third button from the left) 3) Close the window 4) Press command-shift-R to bring up AirDrop. Hi all, AirDrop's "command-shift-R" and menu shortcuts have broken for me, and now brings up this: If I resize the window I get this: If I add AirDrop into the sidebar in the preferences, the shortcut works again. AirDrop functions absolutely fine. Before this, I uninstalled VirtualBox, and it was working fine. Deleted completely unrelated files (VirtualBox files ONLY, I can confirm this, as I've done this on two machines and both have the same problem). Also, sometimes when highlighting and deleting text in Safari, either completely different bits of text are deleted (the cursor basically jumps), and it will also sometimes highlight the text that moves into the space of the text I have just deleted. This has happened with Pages too. Any ideas? Many thanks all!
