Lightbox triggers on mouseIn

Hi,

I am trying to create a drop-down menu with lightboxes. Each button in the header shows a lightbox with other pages to go to. I would like each lightbox to disappear when the next one is hovered on, so you can run your cursor along the top and each drop-down appear one after the other.

I have managed to get the mouseIn to work, but not the mouseOut. Is is possible for the drop down to stay there after the cursor is moved away from the button, but only when it goes onto the lightbox? Otherwise when the user goes to click an item in the drop down, it will dissapear!

I hope this makes sense,

I would appreciate any help!
