Full-screen issues

I seem to have run into a bug when viewing web pages full screen. In Agent & DTpro the down scroll arrow doesn’t seem to work. I’m running 10.3.9 with both arrows at the bottom of the bar.

Far more minor, but also while in full screen mode, if there isn’t a link overlapping it, I can still activate things on my menu bar though they aren’t visible.

I was also interested in continuous scrolling of PDF’s in full screen. Is that a Tiger/pdfkit only kind of deal?
