Maybe I'm doing something wrong, but when I try to use the pan and zoom tool, it doesn't seem to be working right. There is a plus on the right hand side of the zoom adjustment, and a minus on the left hand side. With previous versions, I used to be able to press the plus or minus to make fine adjustments to the amount of zoom I wanted to use. With NXT 5, and actually, with my previous version NXT, the plus and minus have no effect. I can grab the slider bar to adjust the amount of zoom, but that's it. I can use the presets as well.
