Hello!
It seems to me that pyxpcom+xul is dead :)

1) I tried xulrunner from Democracy tv player (it looks like containing
pyxpcom inside)

If I add python code into .xul file, like this
<script type="application/x-python"> 
a=1
b=2
</script> 

xulrunner doesn't display any contents in a window. after removing python
code, displays perfectly.

2) After that I tried to build xulrunner by instructions from
https://develop.participatoryculture.org/trac/democracy/wiki/BuildingXULRunner

build process started, but after xpidl.exe started to work, this tool
crashes saying
"An application has made an attempt to load the C runtime library
incorrectly"

As I can understand, this is because my Visual Studio is version 8, but
mozilla requires Visual Studio 7.1
I dont have VS2003, therefore cannot build xulrunner with myself

3) Also I tried  pyxpcom.xpi + firefox3 from
http://vamposdecampos.googlepages.com/pyxpcom
which works perfect for several minutes, after that crashes unexpectedly
without any reason

what can I do?? return back to tkinter?
I feel that xul is the right way to build gui, but for now is it working or
not?
Thanks in advance,
Denis
