SS doesn't run full screen

(sorry for bad English)

Hi, I have SS 6.4 installed on a clean version of Kingdoms 1.5.
The game works fine, except for the problem that you can see in the pictures:

This is a screenshot of my desktop after run the game.
For some reason the game didn't run full screen.
I tried to reintall both Kingdoms and SS but it doesn't work anyway.

Thanks for the help, and thanks for this awesome mod, I hope to be able to solve this problem

Ops, I just move the Start bar in the bottom of the screen, and it works. :)
