I've encountered a problem writing emails in Yahoo Mail; sometimes the 'Enter' key stops working and does not move the cursor down a line. The result is that I can only write run-on sentences with no paragraph or line spacing.

I've tried restarting my PC and clearing the browser cache and still no good (it works fine in Chrome).

Any help here greatly appreciated.
