	Firstly Thanks to everyone who came up with an idea.

	To force hypercard to update its screen from an XCMD:-

	1. SetPort(hcPort);	{set the graphics port to HC}
	2. sendHCMessage('set lockScreen to false');
				{ only needed if screen was locked}
	3. sendHCMessage('go to this card'); {this updates the screen}
	4. setPort(myPort);	{switch back to my port if reqd}
