"Not ready (again)"
When it works, it's great.
Dropbox v1.4.7 on MacOS X v10.5 (Leopard, on a G5 tower), the finder repeatedly restarts. Selecting "quit Dropbox" allows Finder to run. Haven't checked it on other systems (Snow Leopard, Lion), but hesitate to try it because I use Dropbox frequently.
Dropbox v1.4.7 (at least on MacOSX v10.5 on G5 tower) causes Finder to repeatedly restart.
