As far as the 1st issue goes try using the heal button, "*" on the extended keyboard, "h" on compact, or typing /heal. I'm not sure what the issue is with moving to cancel healing, but I ran into this issue all the time starting out so I just got out of the habit of doing it all together.
The 2nd issue you described I have never experienced, or heard about before.
