Even when using the example on this page this is true:
Use "Date input 6: " and choose a date in either August or September. "Aug" or "Sep" won't be auto-selected on the month pulldown once you've selected the date from the calendar.
Also seems to happen in "Date input 4: ".
This happened when I use both Firefox 3.0b3 and Safari.
Sorry if this has already been posted - I did not see this issue mentioned when browsing past posts.
Thank you very much
