Flex scrollbar doesn't release

Hi there, this problem affects my Flex 3 app when it is being viewed using Firefox for Mac.

If the user drags the scrollbar then releases the mouse OUTSIDE THE BROWSER, the scrollbar doesn't get released and continues to scroll the content once the user rolls the mouse back over the Flex content.

Please check out this link in Mac/Firefox and you will see what I mean:

Anybody come across this before, any ideas for a solution?

Thanks!

Somebody on the Adobe forums just pointed out that this has been fixed in version 3.4 of the Flex SDK. I was using an older version still. If anybody else encounters this problem make sure you have 3.4 or later.
