Event Times & Locations

The cursor used to take you from the confirmed box to the date/time for the event. Now it goes directly to the location first which for us doesn't limit the locations because the default date/time is today/current hour. So what happens is that I select the location (and they're all available) and then select the date/time and very often get the message (when I try to save) that the location is in use at that time. Much better to put the date/time in first and then see what locations are available (which is what it used to be!).  Otherwise, give me an option so I can set the default the way I need it for my use.
