strange colours - flash buttons

[esoterica]

Hello!!

I'm making a site - http://somethingtolistento.com and it's going ok, but wherever I have a button (in my case a vector shape with an alpha of zero) I get a box appearing on the screen a slightly diffeent shade to the background, for seemingly no reason...

This only happens when I set my colours to 16Bit not 32Bit (or thousands, not millions on my mac)

I've uploaded an example here - http://somethingtolistento.com/example.jpg and attached the pic
for those of you who don't see the problem on the site.

Is this a known fault in flash? Or am I doing something wrong, obviously I would like my site to look nice on as many computers as possible, any help would be greatly appreciated!!

Thank-you you're all awesome. :)

Luke.

It simply has to do with the colour setting you use, not with flash itself. The background color seems to be one which just isn't in the 16Bit range and get's rounded down to a closest possible value.
