Here's how to make maximized windows unable to overlap RK Launcher without using any extra programs. All you have to do is:
1. Resize the taskbar to the size of your dock. Resizing arrows will appear if you leave your mouse pointer over the top of the taskbar. Just click and drag. You may have to play with the size of your dock a little so that they match.
2. Restart.
3. Tada!
