Please explain 'parallax' - HUD issue

I'm using a HUD and see everywhere all over the forums "oh lol, set parallax to 0,0"

No where can I find what this means or how to accomplish this. I have seen a few demos which really don't tell me anything either.

Any assistance will be appreciated.

edit: ultimately my issue was I had an anchored HUD and it was really laggy? any solution to this is great.

Thanks

Select the layer, look at the layer properties on the left and you'll see the parallax settings.

This is so much better! <img src="smileys/smiley42.gif" border="0" align="middle" />

I have no idea how I didn't find that, I searched the manuals and forums prior to asking =\</p>
