[Laszlo-dev] How to profile application operation

[Henry Minsky]

No it works in Firefox on OSX, something is screwing up in IE7. WHen I look
at the data packets, there is something odd. The chunks have plausible data,
but then one of the chunks just has "</xml>" in it,and that is not the last
sequence number of data that gets sent (i.e., it is seqnum=3, and then
there's more data in seqnum=4 packet)..
