I've had a bit of an annoyance with some of the dialogues in evolution.
They do not appear in the win list when I press alt-tab. Now I believe
this is because they have the skip taskbar NETWM property set (that's
the only difference to all the other windows I could find). However it
is quite annoying, especially with pointer focus. Because if I don't
immediately answer the dialog, it will disappear behind the full screen
main window and I have no other way to of getting to the dialogue apart
from iconifying or pushing away the main window. I'm not sure if this is
evolutions fault because it should not set the skip taskbar hint.
However I actually understand that if you have a taskbar, you'd probably
not want the dialogue to appear in it. However you'd still want it in
the window list I would think. Reading the spec it says the hint
indicates the window should not appear in the taskbar, don't know if
that should be the same thing as the window list. I'd argue no.
