I've popped in a few times since your post, but haven't managed to cross paths with you yet. You're using 'Weasal' right?   Crescendo left me a ?message for a good idea, to try using the resizer at my default res, and see what that does. Lo and behold, there is an oddity.   First off, simply setting the custom res in the resizer forced my lower windows taskbar to always be on top, even when in game. It basically looked like an active desktop, with no way to get the taskbar to go away. That was using all the same settings for everything in the previous posts/tests. I then turned 'chat window support' OFF in the resizer, and it fixed the problem, taskbar went away. That's when I noticed that the game's "full screen" was dropping a number of lines off the bottom of the screen. As you can see in the screenshot, there are 30 pixels of black space at the bottom (i measured it in photoshop), and the text/chat is cut in the middle of a line... where that line cuts off was the bottom of the monitor at full screen.   1650x1080   http://www.bargeld.us/storage/1650x1080.jpg   Based on that, and the font wonkiness I've seen, it almost looks like there is a fixed value in the formula for the res to display that is off by that 30. Or possibly a weird percentage/division occurring.   I'll continue to look for you in game.   Edit: on a hunch, I checked the height of the Vista taskbar by taking a desktop screenshot and then pasting into photoshop and measuring: 46 pixels.   Edit 2: Feel free to split my troubleshooting stuff off to a separate topic for general Resizer troubleshooting, in order to clean up the mouse aim topic. Sorry about that.
