[AG-TECH] RE: AGVCR

[Derek Piper]

	To further the investigation, I have found that AGVCR doesn't actually 
crash or hang at all, at least not in of itself. By enabling the telnet 
mode, I was able to telnet to it even though the window was 'not 
responding'. It was still receiving and recording to disk just fine. 
Issuing a command 'help' actually got things 'unstuck' on the GUI side, 
so that may be a work around until I can track down what's happening. It 
seems to be again something to do with the GTK stuff though and not 
actually anything with the underlying AGVCR operations themselves.
	This may have been why upgrading GTK made some slight difference to the 
frequency of the apparent 'hangs'.
	An update to AGVCR Launcher (0.4) allows you to enable the 'remote 
control' mode from the Venue Client.

	If anyone has had anything similar happen with GTK apps, let me know.
