Newest version messes up "day" grouping. I use Google calendar .ics files and many events are showing up on the wrong day grouping when grouping by day. When i turn grouping off, the dates are correct. See http://www.uulosalamos.org/weekly-list for the view when day grouping is turned off and http://beta.uulosalamos.org/happenings/calendar/weekly-list/ to see how the day grouping changes the shown dates.
