The event calendar has dropped February (I'm using the multiple-month version which required the download). When we were in Feb. all months were there. Now that we are in March, the previous month is shown as January. When I go to January, it showe the next month as March. Events were entered during the month of Feb., which were saved and would display when this month was available (i.e. while in Feb.)

As the note on the download instructions indicated, I have sen my time zone to PST, although I'm actually in CST.
