Whoops --- no, I did something bad - I let one file from my slideshow
interval patch sneak into this file. You can just undo the changes to
PreferenceDialog.cs and it should be fine...
Here's a new patch with that diff removed...
Many apologies... I regened the patch at the last minute and didn't
check it carefully enough... I guess I should have tried building it
against a clean copy to be sure...
