There's a folder called "WUSS". Click on it, click on the application, click auth, put it w\e you want. 2nd, in the settings make the tree to your sts folder, click add a folder, my tree is "C:/Documents and Settings/Austin/Desktop/STS/STS" and set it to yours.
Drag the small box at the right bottom corner. Test it out, let me know if it doesn't work.
