Bitcoin doesn't install Growl-- something else must have in the past.
PS: there is an open bug in the 0.6 release that it is not compatible with some versions of Growl; if that isn't resolved Growl notifications might be completely disabled.
Hi Gavin. Thanks for the confirmation.
Ok, something else must have installed Growl before. It's still strange that Growl own notifications only started poping up after he started using Bitcoin. Coincidence, or maybe a new Growl release and it's telling him to update it? Like I said I didn't see the exact message, but it has their website URL in it. Nothing to worry about.
