OK, I can see why the challenge number is important. I looked at apeCore.js some more, and I was wondering if a fix could be made on the client side by sending all commands via the APE.Request.Stack or APE.Request.CycledStack class. However if it is the web browser mixing up the calls (so far I have assumed this) then I don't think this will make any difference. I guess you would need to queue up multiple commands, then send them with a small delay between each one, which doesn't sound 100% reliable.
The only problem I can see with the server side fix is how to handle the scenario where you receive chl 1 then 3 but 2 never arrives (due to a bug, network or proxy glitch, etc). It probably needs some kind of timeout then either carry on or fail. But otherwise I think that will work well. Thanks for the quick response!
