Hi Fabian, Thanks for your reply.
The problem isn't manifesting any more. I haven't done anything for it to go away but I'm glad it has. On a related note, should each remote call use a separate qx.io.remote.Rpc variable, or can one be declared for the whole class and be reused? In the code that I posted in my first email I used a separate qx.io.remote.Rpc variable for each function (each listener has its own variable), but I've tried using just one such variable and it worked fine. I was wondering if reusing one variable for different remote calls could cause any conflicts and should be avoided. Thanks.
