Just add this into your AIR app, and run it:
< mx:Label text="Installed AIR Version:
{NativeApplication.nativeApplication.runtimeVersion}"
fontWeight="bold" />
After ages of neglecting to figure out how to resolve the issue, I can now post to this blog again. At some point I could no longer create the body of a post, and blog entries are usually pretty lame if nothing but a Title.
Sounds like the most common fix is to verify you go to the same url as you have in the configuration, specifically paying attention to whether or not you have ‘www’ included.

That didn’t work for me, but now that there’s a new version of Movable Type, I have upgraded to 4.261, and I’m back in business!
