Anyone else have a problem with not being able to move the cursor in the comm with the arrow keys? It's kind of annoying to have to delete half a sentence to fix a typo in an announcement. Sure you can click with the mouse but sometimes you have already gone past the edge of the screen. Not a big issue, just something that kinda bugs me every so often.

If you have scrolled past, you can click and drag to scroll back.
Not sure if this works on all browsers but definitely on Chrome.

have you tried using CTRL+arrow keys to jump forward and backward an entire word at a time?

Yep, I have the same problem. Switch to IE, everything will work just fine

nope, ie has some other issues
