This bug comes from a discussion on this issue in bug 162090 http://bugzilla.mozilla.org/show_bug.cgi?id=162090#c34 Reproducible: Always Steps to Reproduce: 1. Move the window taskbar to the left of the screen and dock it there 2. Open MS-Magnifier (should be at the top of the user screen) Actual Results: All of the DHTML screen property values screen.availLeft screen.availWidth screen.availTop screen.availHeight are not updated in real time. More precisely: screen.availLeft should be > 0 screen.availWidth should be smaller screen.availTop should be > 0 screen.availHeight should be smaller than before the relocation of taskbar and opening of MS-Magnifier. Expected Results: These property values should be updated in real time.

Also, "About the screen.availTop and screen.availLeft properties: Reader Robin Berjon reports that in some instances, these properties are not zero, as stated on page 706. In Windows, if you move the Taskbar to the top of the screen, screen.availTop is 28, meaning that the first available top coordinate of the screen is 28; likewise, if you move the Taskbar to the left edge of the screen, screen.availLeft is 60. When the Taskbar is at the right or bottom of the screen, the properties return zero, because available space is flush with the top and left screen edges in those cases." can be found at the end of this page: http://www.dannyg.com/support/update5.html

This demo case will work for MSIE 6 for Windows and Opera 7 beta 1: note that these browsers will update in real time the screen.availWidth and screen.availHeight property values thanks to an resize event type on the window or document object. Mozilla 1.2.1 does not update in real time all of the screen.avail* property values: these properties are the coordinates and dimensions of the WORKAREA for applications. More details, instructions are given in the demo case.

You searched for dups, eh? This only has 10-15 or so... ;) *** This bug has been marked as a duplicate of 62395 ***

I thought the summary of bug 62395 involved the screen resolution and changing it. Maybe I saw and read the summary of bug 62395 and concluded that changing screen resolution will never ever change the screen.availLeft nor the screen.availTop values. Why should it? This bug 184459 is about resizing the WORKAREA. The WORKAREA can be modified a lot by just shifting, moving, resizing os-dependent applications around and that, without changing one pixel of the screen resolution. That is what the submitted demo case was enlightening. I'm repeating myself here.

verified.
