The dates field allows you to type two dates, with tab to go from outbound to inbound. Doing this re-formats the dates (e.g., "11/2" becomes "11/02") and clicking the calendar control shows the correct date range highlighted. But the "Search" button at the bottom is greyed out, with no explanation of why. Turns out I needed to go to the calendar control and re-select the already selected and highlighted dates. Only then did the "Search" button become active.

Please allow typing the dates.
Please have some error indication as to why the search button is inactive.
