Well I did not work for me...
Got a new laptop, using same ie11 as old laptop. Garmin site says I have communicator plugin and it detects my Dakota 20. Go to geocaching.com and when I try to send to gps, communicator plugin is NOT detected.
AAAARRRRGGGGGHHHHH Help?!
***UPDATE***
Ok that's odd...so I loaded a cache into another ie tab and when I clicked on send to my gps, a little window popped up asking if I want to allow geocaching.com to access my gps. Not sure what I did but it works now!
