[Laszlo-user] catching invalid resources in SOLO mode

[Henry Minsky]

aside from timeouts, I don't know if there is any way in SOLO mode to be
informed of an error in the transport/loading!There might be some Flash hack
to get some sort of status
out of loadMovie, but I don't recall seeing any way to do that.
