Update to 2.5.1 problems

I just update DTP to 2.5.1, but I can’t get the ‘Install add ons’ box to go away.

‘Cancel’ does nothing at all.
‘Install’ makes the box go away, but it comes back as soon as i click in the DTP window again.

Any ideas?

Reboot your machine. If this persists after a reboot I would move ~/Library/Preferences/com.devon-technologies.thinkpro2.plist to the Desktop and relaunch DEVONthink.
