DTPO 2.8.3 PDF service BUG

I just upgraded.

I installed the PDF service.

The updated PDF services is nearly unusable.

The list of groups uses BLACK characters on a DARK GRAY background, making the list nealry unreadable. It use to use WHITE characters on a DARK GRAY background.

This needs correction as soon as possible.

Could you please post a screenshot of the group selector? Which version of Mac OS X do you use? Did you enable any options of System Preferences > Accessibility > Display?
