Probly not a bug but it doesn't look good on the index page.
After installing 5.2 I now had to scroll half a page if I have the calendar option to on.
I shortened the months in english.php but still have a problem when calendar is in the on the right side on index page.
Have a look Here
Remember what you see is with months shortened in english.php
If I leave months as full charcters then I have to scroll about half a page with my settings at 1024 X 768.
Can the calendar be moved to bottom of index page so it might solve this problem with scrolling or can the calenda box be made smaller so it is same size as statistic and top poster width. This would solve the problem if left on the side bar.
