Why do I have a black box over HP Photo Print Software, after installing Windows XP?

My computer was just updated with a newer CPU and Windows XP. All my data was transfered. All my software and hardware was reloaded. Another change was that instead of plugging devices into a USB hub, the devices were all plugged directly into the back of the newer CPU because it had enough available ports.

I have been using an HP inkjet all in one printer for some 6 years . It has a "Photo Print" software that I like for managing and editing photos. Since this change, now when I bring up that software by chosing a picture and clicking on "Photo Print" I am sent to that same photo print screen except that it is covered by a black box that covers the entire screen and hides all the buttons and the toolbar. It shows me the photo I selected and nothing else. It's unusable this way. I've tried calling HP for support but since my printer is so old they won't help me unless I pay for a new warranty. The newer CPU is a hand me down.....not one with a warranty. I don't think it's an issue with the CPU.

Does anyone have an idea why I'm getting this black box on top of the application? What should I do? We've already tried reloading the printer software 3 times and it doesn't change. Is this a flaw with Windows XP?
