The Evolution preferences dialog (Edit->Preferences) opens a dialog that is needlessly tall.  This makes it difficult to use on netbooks and other devices with small vertical resolution (anything smaller than 768px high).  Worse, the dialog is not vertically resizable, so the user cannot possibly see the "help" and "close" buttons at the bottom.

Since the icon list on the left is scrollable, and the accounts list is far larger than anyone could possibly use (it could easily display 30 accounts), I suggest making the default size at least 30% smaller and resizable.
