I've just installed the trial of version 5.18 and a bug from the last version STILL hasn't been fixed despite it being drawn to NCH's attention. After the machine has been in "Sleep" mode, it is a hit and miss affair if VRS will start or not. The VRS service has to be stopped and then started again before it will work.
Added to this, they seem to have introduced a new bug. When the "Find and Play" applet is closed, VRS starts a new recording that lasts for about 10 seconds.
