C# Program runs fine, until minimized

I've never seen this issue before, and I'm not even sure if I'm posting in the correct place.

My Co-worker wrote a C# program (windows), that includes a web control. In that web control are a bunch of iFrames. Now, when the web control is populated (max 15 records), everything is fine. 99% system idle process. But once you minimize the program, boom, 99% process goes to the c# program and stays there!

If the web control is not populated. There is no issue with minimizing and maximizing the program.

There are no functions that run when the program is minimized or maximized, so there's nothing to debug...

The program is crashing on two computers, but on the rest (about 8 computers) it runs fine.

The two computers that "crash", are not very similar... so it's proving hard to find what may be causing the issue. One computer is xp, the other is windows 7, one is ie7, the other is ie8.

If anyone could point me in the right direction, or if anyone had a similar situation and has a solution, I'm all ear's and eye's!

I would attach Visual Studio to the "99% CPU" process, break all, and see what's going on in there. That's first step.
