Hello Philip,

Yes, you're right! I found it myself yesterday.

It was quite obvious with a Javascript debugger, finding where to set a 
breakpoint being the most difficult part ;-)

Thanks!

> Hello,

> There appears to be a very curious bug with the date picker that only

>
> 1) Ensure the date of your computer is set to a calendar month that 
> has an odd number e.g. May (yes really!). I used the date 31/05/2011.
>
> 2) Open a form (see below for included test case) and using the date 
> picker widget set the date to 21^st of February (21/02/2011) in the 
> 'Test Date' control.
>
> Notice that the month in the date field is set to March 21/03/2011 and 
> not 21/02/2011 as selected.
>
> Now to prove that this is related to the machine's calendar month, go 
> and change the month back to June (an even month), do things like 
> clear the browsers cache and repeat the test. You will see that the 
> month does change this time.
