Problem on "change state on mouse hover over"

Hello,

first of all sorry for my engrish!

I've seached through the forum but did't find a solution...

I'm on a "Pick many" slide and i have a problem with normal captions box:

I have this normal caption box (on the base slide) hidden and i want that it change it's state to normal when mouse hover over a picture - one of the choices - and restore on leaves.

It work as intended until you click on the picture. If you do this the caption remains in normal state and doesn't disappear.

I've also tried to move the box on a layer apart, maked a new trigger (show layer <name_layer> when mouse over <picture> and restore on leaves) but doesn't work at all...

Any suggestions?
