Browser still opening on second monitor
Firefox 3.6 worked fine with my setup.. And 4.0 not so much. I'm using Windows XP with 2 monitors, the driver version is 175.19_geforce_winxp_32bit_english_whql. (Geforce fx 5700) Before, I could drag a browser window from the secondary monitor to the primary, hold down shift then click close and it'd open on the primary again. Now, Firefox will open on the second monitor for a second then move to the first. Also, full screen Flash is acting sorta weird with 4.0 as well. Sometimes when making a flash video full screen when the browser is on the second monitor it opens on the first.
The only way I've figured out how to fix this is to close Firefox without saving tabs.
Just to add: This problem only seems to be occurring when using the Nvidia Desktop Manager 'next display button' via the 'title buttons' option. If you just drag the window to your secondary monitor things act as they should.
