Leo Newball: Instant On 4.0.0 itself, on Lion, is the issue. I've edited the post to reflect that. Instant On 3.1 will only run on Snow Leopard, which will be fine.

Patrick Stein: We're certainly sorry you ran into the issue - we've been speaking with devs as we've confirmed the issues with their software. Your app was only recently added to the list, and we haven't had a chance to contact everyone yet. We do have email right on our site though - our contact form goes directly to us. Please get in touch that way if you'd like more details - we're happy to work with you.

Any app devs: We'll likely post more technical information on this issue here on the blog when we post our fix (hopefully later this week), but get in touch if you'd like more details.

Joe Ranieri: We'll likely have more information posted in the future, along with our fix.
