Confirmed also on:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9b2pre) Gecko/2007112604 Minefield/3.0b2pre
from ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2007-11-26-04-trunk/firefox-3.0b2pre.en-US.mac.dmg

I opened two windows and re-sized them so that they did not overlap.

first: http://www.wykiwyk.com/mozilla/pics/pk1001_p1.jpg
second: http://www.google.com

Any page without a big graphic will work for the second. Any page with a big img should work for the first.

When I click on the first window and mouse over the picture, the icon shows a magnifying glass with a "+" in it. I click on the graphic and it zooms the picture out and the magnifying glass has a "-" in it.

The problem is that if I have the first window selected and then move the mouse over the second page, it still shows a magnifying glass and a "-".

The problem is that when I am over the second window, clicking will select the second window. Clicking will not de-magnify anything, so the state of the pointer icon is not correctly matched to the action that would occur from a click.

This may not be a big deal. But this may be a symptom of a problem that would cause problems for accessibility. If a screen reader is looking at the state of the mouse pointer icon, or at something behind the scenes that also sets the mouse pointer icon, to describe what action would occur if the mouse is clicked, there would be an error. If I am wrong, and there are no implications for accessibility, please remove the access keyword. Thanks.

1.  Opened the two windows as mentioned above, and resized so that they did not overlap

2.  Going from the image window selected with the magnifier at "+" did not reproduce this, most likely because the image to be magnified fits in the window and so there is a gap before crossing over to the second window - always had an arrow once my mouse was off the image.

3.  Magnifying the image and going from the image window being selected and the cursor being magnifier "-" to the other window I had about 3 out of 5 times where the cursor did not change once I was hovering over the other window.

4.  Going from the non image window being selected to the image window - this one does not make sense that you would want the cursor to become a magnifier since the operating system requires that you activate (select) the window before it would recognize that magnification is possible.

This might be related to bug 297080.

It definitely looks as though bug 297080 is related. It makes sense that, if the icon is not changing when one leaves a certain area of the screen, other things would show symptoms. Just to get these memes into this bug, these might be:

- mouseout/mouseover events
- tooltips
- popup menu problems (perhaps?)
- first click lost problems
- any others?

I actually have reason to suspect there are deep problems in this area that cut across many symptoms. I recently created an extension and, when I had loaded a problematic popup toolbar button, that popup would steal key events from the entire window. But only on Windows....

So, clearly, there be dragons on this side of the map....
