Comment 41 for bug 751605

I was not able to reproduce this with a Terminal window, but with firefox I get this strange effect when UNmaximizing a new window.

When I open a new window of firefox, it opens maximized on the attached external monitor. When I click on "UnMaximize", it jumps to the laptop display.
The effect appears only on newly opened firefox windows. Windows that have been 'used' already for resizing, etc. do not have this effect.
