I've been having trouble with the rrgas_gps command. When I press the button that i've configured to do it, nothing happens. I can tell that the program is "trying" to do something as the scrolling time/date stamp pauses for a second or two, then continues scrolling. I've made sure my GPS signal is good. I use GPSGate w/ my Garmin USB 18, which works fine with iG. Any thoughts?
