Hi after a monumental struggle, I installed my US TOPO maps from CDs, got Mapsource working, got Mapinstall working, got Garmin Express working, got basecamp working, but my GPSMAP60C will ONLY work with the first app I use of that list. If I try another app, it will not communicate with the GPSMAP60C. Then if I try that ORIGINAL app, it will also not work. If I close an app and reopen it, it will not work. There are no ghost processes I can see in the Task Mangler in WIndoze 10. If I reboot the PC it WILL work on ONLY the first app I use after reboot. It's as if the USB permissions are being locked out or something once I close an app.
Here's all I've tried:
Connecting and disconnecting the USB form the device.
Trying a different cable.
Powering off and on the GPS unit.
Trying every permutation and combination of GPS communication mode inside the device.
Uninstalling and re-installing the USB driver.
Uninstalling and re-installing every program MANY TIMES.
Thanks in advance for your help, excluding all the info listed above, which I've already done many many times.
