Vista Home Premium - desperate!

I have loaded Vista Home Premium and the window for Vista is contained within a bigger black window. I can't get the Vista window any bigger. I had Windows XP and it worked fine. Is this problem because Parallels doesn't support the Home Premium version? Should I go out and buy the Business version. On the box Parallels says it supports Vista but only inside the book it lists which versions it "officially" supports and Home Premium isn't one of them.

 

You need to install the Parallels tools in your VM to fix that problem.

Yes problem solved. Thank you.
