Vides Fill screen on external monitor...

Using XP Pro (with latest upgrades) on high end laptop connected to a docking

station that has an external VGA 22" monitor connect to it.

When I watch a video from a website, on the laptop screen you see what you

would expect, but on the external monitor, the video will fill my external

monitor screen 100%. I normally use windows meda player.

In skype, for example, if on a video conference call, the laptop will be as

expected but the external monitor will be to 100% sized videos rapidly

flashing back and forth between each other.

It's very annoying to have video in full screen because you loose your mouse

and you're unable to to see the program .

Does anybody have any ideas to resolve this issue?

Thanks Bob
