The Big Slowdown: Upgrading from AIR 1.5 to AIR 2.0

It seems that some AIR applications may develop speed issues when upgrading from AIR 1.5 to AIR 2.0. Here is thread from the Adobe Forums. The upshot is that Adobe is proactively seeking a fix. Meanwhile they also offer a method of reverting back to AIR 1.5, should you need to. Here’s a quote from an Adobe staff member:
…below is a link to a tech note that describes how to download the AIR 1.5.3 versions of the AIR runtime and SDK. In addition, it also includes a link to an application that can be used to prevent the AIR runtime from automatically updating to new versions.

I will follow-up with additional details on this issue once we verify whether our internal fix addresses the issue.
