I thought Henry put the change in to get the byte length to agree. Henry?

You may note that the MALFORMED SWF message is still there, so that off-by-one bug in the compiler isn't fixed yet. Dunno if it has to do anything with the further
problems.

The call_method errors are due to 'LzCanvas' and 'canvas' being undefined.

I finally handled to have an 'hello world' trace working.
This is the source code:

  <canvas>
  <script when="immediate">
  trace("Hello world");
  </script>
  </canvas>

Note that 'when="immediate"' is required for this to work.

Also, this *only* works if I wipe out LFC7.lzl, making it
an *empty* SWF (any target version seems fine).


I'm now proceeding by incrementally adding components
of the LFC7.lzl back in, but I don't understand a simple thing:
what language are the .lzs written in ? :)
I tried adding trace() calls there, but w/out success, it seems..
