Fedora :: Xfce And/or Applications Crashing?

I have the xfce 4.6 desktop installed with Fedora 14 x64. First, I started having some problems, not sure if they are connected: the menu button on the panel somehow moved from the bottom left corner by itself, the window manager won't open, all windows (browser, programs, etc.) are cut off so that the strip with the minimize/maximize symbols up in the top-right corner is not visible, all windows open in top left-hand corner of screen and can't be moved, workspaces disappeared form the panel, unable to switch windows (have to close the window in focus to access another), typing in some applications (terminal, text editor) does nothing sometimes but works when I reopen them, etc.

.. After this had been going on for a while (few hours), I was changing the panel icons, and the bug report icon suddenly showed up and said that package gnome-1:0.8.1-10.git20100831.fc14 of the gnome network manager (xfce doesn't have it's own network manager?!) and the ibus keyboard layout switcher plugin had crashed. These don't seem to have anything to do with the troubles I'm having; the internet works fine. I have copies of the bug reports but I'm not sure if I should post them since the bug reporting tool warned me that they may contain sensitive information.
