Problems making a double-rollover

Hi there.

What I am trying to accomplish:

When the user mouses over one image, it has a standard mouseover effect.
Simultaneously, it has a disjointed mouseover- an image elsewhere on the page
also uses a rollover.

I know how to do each, but when I try to make it use both at the same time,
when I mouse out, it doesn't swap out one of the items (it stays in the state
it changed to on rollover).

I imagine this means I'll need to tweak the behaviors/code, but don't want to
just fiddle around for an hour.

Anyone been through this and found a workaround?

thanks.
