How-To: Get your Growl back from Logitech

For the past few days, since running some updates on my MacBooks, Growl's not been showing any messages. I've since found out that it was Logitech Control Center blocking the messages. The solution is quite simple, delete /Library/InputManagers/LCC Scroll Enhancer Loader then log out and everything should be fine. Thanks Zamboni.

Note (9 June): Growl 1.3.0 has a work around to combat this problem.
