Animated rollover on top of an animated rollover?...HElp!

I have been struggling with a particular problem that I hope I can get some help on.

I have a MC with a horizontal bar that appears on a rollover - goes from a 0 alpha to 50%. In that horizontal bar are some thumbnails that I want to have a animated rollover action when you rollover them while the horiz. bar is still visible due to its rollover.

THE PROBLEM:

The rollover action to make the bar appear overrides the thumbnail action - if I put the thumbnails on TOP of the bar (in the layers) then when I roll off of a thumbnail I then trigger the rolloff action on the grey bar.

I simply want to make the horiz. bar appear - stay there while moused over - but at the same time I want to make the thumbnails animate when I rollover them while the bar is visible.

I have looked at the tutorial at :

Any help would be greatly appreciated…Thank you in advance
