I noticed that when I enter full-screen mode in Mathematica 9 (F12 for Windows) using a magnification of 125% (or any other number higher than 100%) there is a horizontal scroll bar at the bottom of the screen taking up space, provided that the original windowed notebook had lines long enough to warrant a horizontal scrollbar. This wouldn't be particularly annoying if it weren't for the fact that it's doesn't actually seem to do anything at all; clicking on it moves the scroll bar around, but nothing actually happens onscreen because fullscreen mode automatically wraps everything to the page. For some reason, it still thinks it needs a scrollbar, however, but it doesn't actually work.

I suspect this is some kind of glitch/oversight for the frontend? Here's a screenshot (small preview below):

enter image description here

A simple workaround is to collapse all code into their corresponding orange code blocks onscreen at the time, change magnification to the preferred value, enter fullscreen, and then expand all orange code blocks (at which point the horizontal scrollbar will not load). However, I feel like this kind of editing gymnastics shouldn't be necessary in the first place. If anyone can confirm or deny that this is a frontend visual bug, I'd be glad to hear about it.

Blimey! How do you read that? o_O –  Mr.Wizard Jan 7 at 3:22
It might just be my monitor, my monitor is pretty bright and so the background looks light tan on my screen. –  DumpsterDoofus Jan 7 at 4:23
This might look considerably different depending on the gamma setting. Ideally monitors should be color-calibrated. I haven't calibrated mine (you need special hardware), but I corrected it approximately by eye, and this definitely looks dark brown. –  Oleksandr R. Jan 7 at 13:14
Sure, though the background color isn't really the issue, it's the glitched scroll bar. –  DumpsterDoofus Jan 7 at 17:22
