After updating to Ubuntu 10.10 (Gnome), KMyMoney now opens in fullscreen mode by default, and I can't find any option to get out of fullscreen. I've tried pressing F11, and I've taken a pretty good look through the view options, but I can't find any way to turn off fullscreen mode. After a little looking, it seems like KMyMoney's preferences can't be found in gconf-editor, and there doesn't seem to be a command-line switch for turning fullscreen on or off. So I'm at a loss, and any help would be much appreciated, thanks!
Kmymoney is not a gtk/gnome application; it doesn't use gconf. That's the first thing. If you are using compiz, there is a fullscreen shortcut (usually super+f).
You can try that first. If that does not work, then try accessing the menu by pressing alt+f or f10. Some kde applications start in full screen mode under GNOME (I've never found out why, sadly). If all else fails, someone may be able to provide more information than me.
