[AG-TECH] Release of AGVCR - recording AG sessions

[Derek Piper]

	Hi Monika,

	Yup, it was a known issue, I mentioned it in a post yesterday evening, 
but no problem if you missed it.
	It was a display problem in the end, for some reason Windows doesn't 
seem to like doing vsnprintf() with multiple arguments - sometimes. Same 
code on Linux worked.
	VIC and RAT do not automatically start. In the documentation it states 
how that behavior works, i.e. the '-x' option. For standalone, i.e.'-x', 
usage, AGVCR also requires the mbone tools to be in the same folder or 
path as itself. Please see the docs for more.
	I've posted a new source tree and windows binary on the website now, it 
fixes the display problem.

	Derek
