It may be unrelated - but it appears that after upgrading to Safari v 3.1 and the latest Apple Security update (March 22nd or 23rd), my menu bar icons for NUTD&C have disappeared from the menu bar.

Is anyone else experiencing this problem?

No amount of toggling the preference in either app and re-starting seems to make a difference. So far I've tried a few suggestions from the knowledge base, but without success.

All other Menu Bar icons are working including QuickSilver, Skype, Google Calendar and Mail, Intego, UPS, iSync, Bluetooth, Airport, volume time date, and Spotlight.

Any thoughts?
