So that's a drag.
Still, I look forward to trying it out one day.
In the mean time, yesterday I got a little pop-up saying that there was an update to Growl available. I'd never even heard of Growl, and wondered what virus I might have...Turns out that some apps are using this little third-party tool to display notifications, including Adobe Creative Suite 5. I think - though honestly, I'm not sure - that I might have installed a trial version of one of the those apps on this machine a while back, but I have no idea.
Anyway, it seems I'm not the only one to have had this happen, as the good people at Growl have a page that covers it:: Applications that install Growl without your permission
