Firefox & Thunderbird only open to primary monitor after 10.04 upgrade

[zeero_k]

A small annoyance after upgrade to 10.04:

I have dual monitors. When I start up either Firefox or Thunderbird, the application will only launch onto the Primary Monitor. In 9.10, they used to open on whatever screen the mouse pointer was currently residing in, which was a behavior that I really liked. Now when I start Firefox or Thunderbird, they initially start on the monitor with the mouse pointer, but then immediately jump back to the primary monitor.

Anybody else having a similar issue, or know how to turn off this new "feature"?

I'm using an ATI Radeon 9000 video card and the fglrx driver, no desktop effects.

Thanks.

Bump.

This is especially annoying if you are using your laptop to drive your external monitor - with the laptop closed and put to one side.
