rich:calender closes when month or year changed?

[supernovasoftware.com]

I have many rich:calendar in my application. For some reason on one page it works sporadically.

Most of the time is just closes when the month or year is changed. It works fine if you select something from the current month.

I see no errors in FireBug.

I am using RF 3.2.1 and FF3.

All other places the calender works fine.

Could someone please suggest a way to debug this or a workaround?

Has anyone else run into this problem?

I have still not been able to narrow down the problem. I cannot reproduce it so it consistently so I it very hard to debug.

Any idea what might cause the calender to close when the month is changed?

Has no one run into this before? There has to be some conflict somewhere.

Any advice would be greatly appreciated.
