Correct. And I'm not using a no-multilib profile, either.

I haven't run a dual-card setup. I have two systems I can relate to.
One is a dual-E5345 system with 10GB of RAM, and one is a Phenom 9650
with 8GB of RAM.

I haven't run a multimon setup in a while. I sacrificed one of my
displays as a debugging display for another machine.

What driver are you using? About 3 years ago, I had a setup going
where I was using both my onboard ATI RadeonHD3200 and an nVidia
GeForce 210 with five displays split across the two. Flash never
*crashed* on me, but it did get extraordinarily confused whenever it
came time to fullscreen.

(I did eventually switch to using an ATI Radeon 5770, but only because
of the headaches trying to manage things with two different
proprietary tools. You could do some scary stuff at the time. I don't
know if that's still possible. I'm certain I was running an
unsupported configuration...)

I'd bet on it being a driver issue.
