I loaded up my saved game to play earlier today and found that the combat log window had somehow moved down so that the top of it was barely visible above the bottom of the screen. No amount of click dragging would bring it back up. So, after finagling with a variety of options including changing the resolution to something lower and back and scaling the UI, I can now see the bottom outline of the combat log window in the bottom right of my screen as well as the down scroll arrow (there's no corresponding up arrow). However, nothing in the game is being logged to the window! I'm playing at the native resolution of 1920x1080. Here's some of the things I've tried to fix it:

1) Deleted my uilayout.lsb file
2) Reloaded from earlier saves
3) Started a new game! Still did not help.

Any ideas?
