712839 - Modal window issue with printing dialogs on Windows 7 64 bit

Status: RESOLVED WORKSFORME

(Core :: Printing: Setup, defect)

Description

[John Morrison [:jrgm]]

Steps to reproduce:

1) Reboot a Windows 7 SP1 64bit version
2) After reboot start Firefox.
3) Place the firefox window in the upper right corner of the screen
4) Enter 'about:' in the firefox url bar
5) Hit Ctrl-P to print the page
6) In the Print dialog, select 'Microsoft XPS Document Writer'
7) Click OK

Firefox presents a dialog "Printing...", and also calls up a
file picker. The problem is that the file picker window is
behind Firefox and not visible to the user giving the appearance
of a hang. Clicking on the two visible window, will eventually
label them as "Not Responding".

The user can though get out of this situation by moving the
Firefox window to reveal the file picker, and giving that
focus to bring it forward.

Note 1: the file picker is behind Firefox only on the first
time after a reboot. However, if the user clicks on the
Firefox content window, it appears to be back in the
same apparent hang.

Note 2: this bug does not happen on Windows 7 SP1 32bit version,
or on Vista SP2. On those systems, the file picker is always
the top dialog, and the z-order of the file picker, Firefox,
and the "Printing..." dialog cannot be changed.
