Agreed, the webkit engine used in Adobe AIR is old, however - I’m no JS guru so I could be wrong - if I’m not mistaken, not much (if anything) has changed in the last few years regarding JavaScript. Again, I could be wrong about that though.
I’ll see if I can come up with some answers, regarding the logout, but so far I haven’t had much luck.
I have invested a lot of time (2+ years) in these applications, but it looks like I’ll have to drop them because of the recent changes. Sad really.
