I just upgraded from 1.4.3 to 1.4.4 and now the CSS for the plugin is completely messed up. For example, instead of events having a box with a solid background on the calendar, now it gives a background behind the words only, with spaces between lines, making it look like the words are highlighted. It looked a lot better when the event was in a box instead of highlighted.
Also, the box on the post page itself with the information about name of the group, date, location is no longer in box. Looks like the background disappeared there too.
I changed themes to see if that affected anything, and the formatting stays the same no matter what theme is used, even the default theme that comes with WordPress.
Not sure if this was intended, but it looked a lot better the old way.
