Hi, I've had a lot of fun with Scratch since I started recently and I've had a problem which seems to appear only on my home PC (otherwise I use Scratch on the school's laptops w/ Chrome).

From what I gather, the bug only occurs when right clicking in the editor, shift clicking works properly for me. Essentially, after right clicking, the editor stops recognizing my keystrokes (which is quite a pain as I then cannot change any values in any block). The only thing so far that fixes it for me is to switch tabs in my browser, which becomes quite annoying as right clicking is not an uncommon action in the editor.

Thanks in advance.

My browser / operating system: Windows NT 10.0, Firefox 56.0, Flash 27.0 (release 0)
