Using IBM T61p laptop and second Monitor (DVI connection from docking bay) IBM thinkvision, when browsing in Monitor screen the browser does not refresh correctly. It takes at least 3 times as long to refresh a single page. IE works fine and Safari works fine. 
Firefox refreshes normally on laptop screen but if you drag to second monitor things go wrong.

2. Open browser in primary screen (laptop) use

Does disabling Hardware Acceleration under Options/Advanced/General help?
Is your Issue reproducible when you disable the Hardware Acceleration via "Options"/"Advanced"/Tab: "General" and restart Firefox?
If yes, please post you Graphics Information you can get via about:support resp. "Help"/"Troubleshooting Information" after you reenabled Hardware Acceleration.
Started Firefox this morning and Beta 11 update started. Beta 11 seems to have fixed this issue. I can no longer test this with b10 software as b11 auto installed, so cannot get to root of problem. Suffice to say that b11 fixes this problem so changing state to resolved and cannot be replicated without b10.

I can still reproduce this issue with beta 11.

The issue is not reproductible when I disable hardware acceleration via
"Options"/"Advanced"/Tab: "General".

I'll do that next Monday when I get my hands on the laptop. It is a fairly standard configuration (Intel HD graphics, Windows XP).
