Double click on titlebar doesn't maximize/restore windows

Question

I used to be able to double click on the titlebar of windows and they would maximize, and return if I double clicked again once maximized.

System → Preferences →Windows under the Titlebar Action option is on Maximize.

But when I double click the windows just scroll up (Shade Window).

How can I change it back?

Answer 1

Make sure it is set correctly in the GConf setting database (the Windows utility should do this, but it can happen):

1. Hit Alt + F2 and enter gconf-editor

2. Navigate to apps ➜ metacity ➜ general ➜ action_double_click_titlebar

3. The Value should be toggle_maximize, set it to that if it isn't already.
