Hi matiboy!

I realize this is nearly 3 years down the line but I'd like to ask you about the postEvent glitch that SL4A had with Javascript. I noticed you made a post about it back then on the SL4A board and someone advized you to file a bug report. Have you made any progress with this issue of Javascript not catching a Python response event if it is too fast? I'm stuck one the same problem and you are the only person I could find that experienced something similar.
Hope you'll see this!
