I can't really undestand whats happening, but sometimes editor just wont allow me to edit _some_ strings. It's actually super annoying.
Locks looks like that: suddenly string wont edit. Just wont. I can edit +10 lines string below or above, but cant type anything in the current one. Backspaces work, cursor works, but no typing at all.

P.S. And fix forum visual editor to work in latest Opera
