Photoworks Scene Settings

Hi,

I am having trouble with Scene Settings reseting themselves after Ihave changed them.
For instance; I may change the room length then click apply, thenit will revert to the last room length. I have also unclicked the'preserve length/width ratio' to see if this makes a difference.The 'resize automatically' button is un-selected too.

Can anyone help here? It is very annoying that the settings revertback.
