(FMX) AS Function issues with Mozilla FireFox

There are 2 identical pictures, 1 monochrome and 1 colour on different layers (colour on top set to 0 alpha) inside an _mc which itself is inside an _mc - when you mouse over the mc the colour picture’s alpha increases and hence appears to ‘colour’ the _mc in . . . Really simple right?

. . . and it works, but only when I preview it in flash (ctrl+enter)

when I view it in Mozilla Firefox I only see the colour image . . .

Uh, just went into IE and it works fine . . . . Oh well, if any one needs some code that works in IE here it is:

and if anyone has any thoughts why this fails in FF I’d be happy to listen (off to search more forums) . . .
