Or rather... Calibre started once for me and then not again. I reinstalled, then the same thing, it started once, then after quitting and trying to restart nothing happened. Then I downloaded the latest version, then tried again. It booted once, I tinkered with it, then quit and tried again, no dice.

Curious, I tried to open it from the command line with "open -a calibre.app"

It didn't open, but I got this error:

LSOpenFromURLSpec() failed with error -10810.

Any ideas?

I also took a bite out of the console log:

this is a nasty little bug that seems to affect some users on 10.5.8

easiest fix is to upgrade to 10.6 or you can workaround it by launching calibre as

/Applications/calibre.app/Contents/MacOS/calibre

Thanks for the quick reply!
