In dual monitor setup firefox 9.01 menus blink in and out

Every version of firefox AFTER the 3.6 series has problems in dual monitor setups and I want to be able to keep all tabs I had open when I close firefox so when I open again they are there. In dual monitor if I use monitor 2 for firefox (which is the way I use it) the menu blink rapidly when I click on them and make very hard to navigate. What is it with the video setup in win7 I have to use an older version of winamp due to tearing in the second monitor? Have all you companies not fully learned who to implement dual monitor setups properly or is that not really a concern?

Chosen solution

Firefox doesn't always play well with a multiple monitor setup and hardware acceleration.

Try to disable hardware acceleration.

Thank you no more menu blinking. I guess they introduced hardware acceleration in version 4 or changed how it works because 3.6 didn't have the problem.
