I upgraded to latest 2.3 version yesterday. I have just noticed that when you try and use the minicalendar to select a date, the month name at the top of the popup is one month behind. The grid of days and dates is correct, just the name is wrong.
I am using the Rocket theme but changed a course to standard theme and had the same issue. I have tried different browsers and no difference there. I am presuming that it is something in the yui but have no idea where to start looking.
Would appreciate any help!
