Theme Overlaying Problems.

Hey guys again.

Having an issue with my site in Firefox only, Not IE, only firefox.

Using Dark Blix 1.4

The youtube links, are being overlayed by something, you cant click on the youtube videos. Everything else works fine.

Im using Viper’s Video Quicktags 3.0 to link the youtube videos. If I use the Normal youtube embedding it destroys the theme somehow, removing the sidebar, and anything else.

Can anyone help with this issue? so I dont have to look for a new theme.
