unstable? haven't witnessed that.
Mind of their own? Well I can understand if you dont fully grasp your options yet that it could seem that way ... but until you try to work with it and learn it you will never get comfortable with it.
I dunno, one day I said to myself, Id like to be able to right click in a list and get a popup menu. So I went to find out how. Found out and did it. End of story. I wish you the best of luck.
