If your TUG screen is off-center and the top bar is off-screen, preventing you from dragging it back in view you can take the following steps to fix this:

- Select the application in your taskbar so it's the active window.

- Hit Alt+Spacebar (This will open the window's menu)

- Hit "M" (Shortcut for the Move option in the menu)

- Use your arrow keys to move the window. (after a few arrow key taps it may be attached to your mouse pointer and should then be able to move it with that too)

Once the window has been re-positioned that way, it should launch from that spot from then on.
