Need help with scrollPane boundries

Uncategorized
1

I am using the freeTransform script found at senocular.com. First, here is what I have; a combo box, thumbs scrollpane and a room scrollPane. When the movie starts I load an XML file into the combo box.

If I click on a label in the combo box, those items appear in the thumbs scrollPane. If I click on one of these thumb items, that item’s swf is loaded into the room scrollPane. Everything so far so good.

The freeTransform script is part of the swf that get loaded. So if I click on a swf in the room scrollPane the freeTransform script fires and everything runs ok.

I have 3 problems, any mouse events applied to the room.content prohibits the freeTransfrom script from running. I am not sure why. I am not sure if having the freeTransform script embedded in the swf is the correct application of this script. Although it seems work ok this way. If I remove this mouse events the script runs correctly as stated earlier.

The second problem I need help on is how to keep the swf constrained to the boundries of the room.
The thrid issue, I want to be able to click on an item in the room and clear it or remove it. I have this working somewhat in the clear_btn function only it removes the items in the order they were added which I don’t want, I want to click on an item and remove it.

My code is pretty simple so I’ll post it here, maybe someone can help.
