- Setting screenX or screenY causes window to be resized to its previously redused size
- In order to see the whole window window.screenX must be 1 while window.screenY must be 0

This report actually contains 2 issues (should have been 2 reports)

Issue 1:

Twice as bad as before (same when running in safe mode or not):

Steps to Reproduce:
1.Open Error-console, maximize window
2.evaluate alert(window.screenX) and alert(window.screenY)

Actual Results:  
window.screenX = -8
window.screenY = -8

Issue 2 (regarding setting screenX and/or screenY):

Setting theese attributes has no effect in safe-mode (disabled) but now works as expected in normal mode

Mozilla/5.0 (Windows; U; Windows NT 6.1; nb-NO; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10

Created a new profile and tested as requested - same result

window.screenX = -8
window.screenY = -8

I dont mind checking this but ain't it more easy for the developer to check this himself? Very easy to open the error-window, maximize size and evaluate
alert(window.screenX) and alert(window.screenY) in the code-field

This is actually normal behavior on windows: Any maximized window is moved to negative coordinates and has its width/height (including border/padding) set to the resolution + (border + padding) * 2 to hide the fact that those elements are not removed. If you're bothered by this, you're just going to have to get over it; this hasn't changed since '95 at the least, and possibly traces back to the first window-managing GUI created.
