"Move to" action hides object if triggered twice

Hiya,

I have an object on the page and a button with an action to move the object to specific x/y co-ordinates. If the button is clicked a second time the object vanishes! Looking at the html for the page, it seems that clicking the button a second changes the visibility of the object from "inherited" to "hidden".

I have come up with a couple of workarounds, one of which is to include an action on the button to show the object, but I was wondering whether anyone else had experienced this problem.

Cheers

Stephen
