weird keyboard problem

[Conroy9]

If I hold down both shift keys on my inspiron 6000, some of the letters don't work (specifically, czmxytv). I tried on my friend's compaq 1090 and the same keys don't work! Trying on a toshiba satellite something, different keys (b,a,n) don't work.

Any ideas?

Toshiba Satellite M60.

edit: Btw, why is this a problem? You only need to use one shift at a time anyways.

It's not a serious problem, just my poor typing habits
I generally pick a random shift key to use depending on what other fingers are busy/lazy, and end up pressing both pretty often somehow, especially when I type something that's all caps.

And I'm curious about what causes this.

The same keys don't work on my T42.

That is seriously weird.
