[ct-user] help please

I have just installed CT-win on my pc.
Using Windows XP-home.
When I close the programme a black screen is displayed.
The programme does not shut down and I have to click on the X on 
the upper right corner.
What do I overlook? I can remember that there was a possibility to 
let windows shut down programmes automatically.
Some tips would be appriciated.
