No patterns in color picker

Hi,

OmniGraffle 7 has color patterns in the color picker. However, when I choose and object and try to assign a pattern to it there are no patterns available. Anyone know where they are hiding or what incantations are necessary to make them appear?

Thanks,

That’s rather peculiar. This is an Apple-provided control. Does it work correctly in other apps on that Mac? What version of OS X is it running?

OH! I just hit this myself. The slider for both foreground and background are at 0% opacity—invisible!
Move either the foreground or the background opacity slider up, and hopefully your patterns will reappear.
