The installer for the Finder context menu plug-in on a Mac is still a PowerPC-only application.
This makes it operate slower than necessary on Intel Macs. This isn't really problematic as you really only need to use it whenever you install a new version, but still...
Oh, and the feature to automatically restart the Finder doesn't seem to work either.
Anyway, in the light of Snow Leopard and the goodbye to PowerPC emulation in the OS, this installer is really in need of a minor overhaul. Something to consider for a next release I guess.
