Tab Objects in Web Direct, flashing, on hover

[@Zav]

Hello,

Having a bit of an issue with tab objects, blinking, or flashing in Web Direct, when moving mouse over tab object.   All states (active, inactive, hover, and in focus) are set to "FFFFFF", but on hover, the tab object appears to go Transparent, which creates this sort of flashing effect.  Could this be CSS related?  Is there something else I should be looking at to fix this?

Thanks!
