I have never experienced #1 in Vista, so it is probably some choice of settings in Vista that causes it.
I can confirm #2, however. If I have more text in the edit box than fits on the visible screen and I'm at the beginning of the line, I cannot highlight the text with the mouse and "scroll" to the end. It will only go to the end of the visible area. It does seem to scroll about 1/2 character to the right beyond what fits within the visible area, but that's all. This is on Vista Ultimate w/o SP1.
