Scroll wheel issue.
The zoom feature seems to respond to the number of lines scrolled when the scroll wheel is used. This shouldn't happen. Clicking the scroll wheel one click should do the same thing as hitting the + or - sign in the top-right corner. If you have your mouse settings set to scroll, say, 6 lines per click you seem to get about the same zoom as hitting the + or - sign 6 times. It should just be the same as hitting it one time.
It has always been this way. I just never noticed before that the + and - signs had reasonable jumps in zoom because I always used the scroll wheel and got very unreasonable jumps.
