Bug#940126: Window Buttons aka tasklist no longer works with dual monitors
WindowButtoms aka tasklist is no longer able to group windows by title and
I have a dual monitor setup, with a panel containing an instance of tasklist
on each monitor.
In all previous versions of tasklist, if I moved a window (say Firefox) from
one window to another, I'd get a button for that window on THAT monitor. Same
if I started a new window on that monitor. In short, it worked.
Now, if I check the "Show Windows from All Monitors" option in WindowButtons
prefs dialog, **all** windows for a given app are grouped on the tasklist in
my primary monitor.
If I uncheck that option, they just disappear from the tasklist - they DO NOT
appear on the tasklist on the secondary monitor.
In no case do I ever get a button for any app on the tasklist on the second
monitor. The second instance of tasklist is useless.
So, I have a choice of having all buttons grouped on the primary monitor, or
having the buttons for some windows just vanish entirely.
