When I run graphical programs in GNOME shell, they sometimes (but not always) start with "Always on Visible Workspace". I don't know what is different between the times they do and don't start in that mode.
How can I prevent that? I almost never want programs to start in this mode.
The programs affected include firefox (which I always start from gnome-terminal) and gnome-terminal (which I always start by clicking on an icon). I think I've seen the problem with other apps too.
I'm using X.org. As far as I can tell I'm not running anything like devilspie that might be likely candidates to interfere with this kind of thing after X programs have started.
