I've found that if I double click on the title bar of any of the office applications, it maximizes the window as expected, but prevents any further resizing. On applications that I have never double-clicked the title bar to maximize, I'm able to maximize, restore, and resize the windows as expected. However, if I've ever maximized an application window by double clicking the title bar, it can never be restored or resized (I haven't found any workaround to this, either, short of re-installing office). Minimize works as intended in all circumstances.
I'm running Ubuntu 8.10 (Intrepid). I've tried with compiz and metacity as my windowmanager, with no change depending on which windowmanager I'm using. If I am using compiz, I can use the Expo (Expose) plugin to move the window between desktops but it immediately snaps back to it's old position as soon as it regains focus.
Any thoughts? Any additional information I can provide that will help?
