Multiple Grids on a page with multiple dhxCalendarA excells

I have 2 grids on a page each with dhxCalendarA excells in them.  The first grid initialized works fine, but the second grid’s calendars have a problem.  They don’t close when you click on a day, but if you hit enter, it closes and changes the date.  I verified this with the sample calendar_grid.html by adding a second grid.  I also tried using one grid with dhxCalendar and the other with dhxCalendarA on the same page, but I had the same problem.  Can you let me know if there’s a fix?
