Am encountering the 2nd (no scroll) and 3rd (tasks vanished) problems as well. Thought it was just me. Haven't been able to reproduce the 3rd problem reliably, seems to happen at random. Sometimes even occurs in-game for me too.
Even after clearing the bind for Ctrl+R (reset map), Ctrl+R still doesn't fire off Healing Word if it's bound to R. The ++HardTargetLock bind works well as a workaround (Thank you sglider!) but still doesn't fix the root issue that something as fundamental to the UI as using the default 'Focus' and your R encounter skill…
I was wondering the same, and yea a google search wasn't as helpful as I'd expected, nor were the wikis. However, then I did a forum search and was pleasantly surprised by this perfect thread: http://nw-forum.perfectworld.com/showthread.php?118661-Horse-Coats-and-Rune-Stones Gogo community spirit.
