Try the new GPS DLL's floating around. They seem to solve a few issues (Battery, Stuck GPS, Stuck Data Link).

Sometimes, depending on time of day and your environment it can take a few minutes to lock no matter what you do. Google maps will almost always say GPS Active(0) fairly quickly and have a blue dot with blue background (zoom out your near nigeria). If it does, you're golden, but you have to wait for sats. If you don't get the sats you gotta get better signal (go outside). If you don't get GPS Active (0) in say about a minute your GPS is probably hung. Reboot.
I have no problems at all using COM4. It works fine without GPSGate using gpstest. The only time I use gpsgate is with iguidance. I do also think it is best to use the intermediate drivers whenever possible. I think the updated DLLs are the most important thing. It appears to me that I am getting better coldstart locks too with the new .DLLs, perhaps simply because they close/exit gracefully instead of locking the gps
