Devonthink Pro takes forever to quit

I’ve been experiencing a lot of slowness with DT Pro lately. Launching has taken awhile and now when I try to quit, it takes forever, to the point where I have to force quit. I have all of the latest updates to DT as well as OS 10.5.8. I am running on a G4 Powerbook.
Any thoughts?

Which version are you using, how much RAM does your computer have and how large is your database? V2 is faster than v1.x and usually this shouldn’t happen as long as there’s enough RAM available.
