New Garmin Explore OSX Unable to define Custom Date Range.

I note that there is a new OSX user interface.  I am unable to define a Custom Date Range in Garmin Explore on OSX.   Freezes up. 

Funny:  I just tried post this simple observation, and I received the message " Your posting frequency has exceeded allowed rates.  Please wait 5 minute(s) to post again."

I had not knowingly posted previously.  Certainly within the last 5 minutes.
