I have the same problem. I installed litestep for the first time, and when I was going through the read me and getting familiar with what does what, I clicked on the left side of the "Start Button" and it made the start bar go to the top of the screen and resized my window at the same time. I was like.."Cool", so i clicked on it again and it put the start bar back on the bottom. but my internet explorer window didn't resize. Now when i maximze the window, I have that blank space above the window and can't fix it...I've tried all the suggested solutions even uninstalled litestep...still no fix....what possibly could it be?
