With no warning, this version trashes itself if you are using 10.4, and a simple retrieval of version 0.9.1 then doesn't work. This is not just poor etiquette. This is tantamount to releasing a WORM for users on 10.4

I'm glad a previous reviewer found the trick to downgrade back to 0.9.1 - you have to disconnect from the net (or define a "location" with no network connections, which is easy) and turn OFF the automatically ON "check for new version" in the preference of 0.9.1

Then at least 0.9.1 works again.

Bad job, guys.
Plenty of programs out there are compatible back to 10.2 - please, please make the new versions compatible to at least 10.4.

10.5 is massively buggy, and has no classic. It is not an option for me at this time. So please don't focus only on this newest but unusable version of the Mac OSX
