Windows 2000 or XP, dual monitors, build 2002031104

When setting the background properties of an element via script or CSS the
property is momentarily set then quickly reverts to its original state on screen
(flickers on briefly).  This occurs with setting a background image or color.

This may be related to a UI bug where the background color flickers off on menus.  

Two testcases follow:

______________

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"" xml:lang="en" lang="en">

    <head>
    <title>hover testcase</title>
    <style type="text/css">
        a:hover {background-color:#0054aa;color:#ffffff;}
    </style>
    </head>

    <body>
        <a href="">mouse over to see hover bug</a>
    </body>
</html>

Note this only occurs in the second/extended monitor.  If the window with the
test case is dragged to the primary/first monitor there is no problem.

The may be related to bug 134548
Confirmed on Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9+)

BuildID:    2002040203

Also, if the link area spans accross both monitors, and the cursor hovers over
it on the primary monitor, it's fine, but in the secondary monitor, it has this
problem.

Also, the same problem occurs if the secondary monitor is set to be above the
primary monitor, so it's problem a negative coordinate problem.
Additional note that I forgot to mention:
This only happens if the secondary monitor is above or to the left of the
primary monitor.

If anyone can reproduce with a nightly build, please reopen.
