Megawizard rendering problem with Quartus 10.1

I just installed Quartus II 10.1 on Windows XP SP3.

I am getting a currupted window when I open the Megawizard window.

I tried to open SOPC Builder and the wizard from within the SOPC Builder, but things look fine there.

I have no problem with Quartus II 9.1 SP2.

Anyone see this kind of problem?

Any Ideas what I could do to work around it?

Thanks
