Opening Open and Save Dialogs at a Specific Size
From Birnam Designs Wiki
A problem with Ubuntu 8.10 x64 seems to be ridiculously small Open/Save dialog boxes. They appear to start at the minimum size possible, and users have to resize them every time. A very small percentage look right.
You can fix this by adding a Window Rule to your Compiz Fusion settings (you will also need to enable the Regular Expression plugin):
| Sized Windows | Width | Height |
|---|---|---|
(title=^Open .* | title=^Save .* | title=^Enter name .*) & !(name=Navigator) | 800 | 650 |
The !(name=Navigator) condition is to prevent websites like OpenOffice.org from triggering this.
