The options dialog does not properly resize. Here is a screenshot of the dialog on my 17" 1600x1200 screen:
I understand that this is a popup window that's not really meant to be resized. But why should it be limited to using just a small portion of the screen? At the very least, there's really no reason to have scrollbars here, when so much screen space is available. Also, the fonts could stand to be a lot bigger here, to make the dialog more readable.
