Losing a Group's memory

[Graham Samuel]

I have a group consisting of a couple  of images which I distort from 
within a handler in order to give a simple animation effect of a shutter 
shutting. This works fine, but when I edit the group and change the size of 
one or more of the individual images (for example if I change the height of 
one of them) and stop editing and go back to my 'distorting' behaviour, the 
image(s) reverts to its/their original size. Likewise, if I alter the 
height of the whole group, it also reverts to the original height during 
the shutter animation process, although there is nothing in the code of the 
handler to make it do this.

This must mean that the group retains a memory of the size of its 
components. I don't want this - if I want the height changed, I want it to 
stay that way - so I need my group to 'forget' this original-size 
information. Does anyone know if there is any way of doing this? If not, I 
will have to re-craft my images in some kind of image editor and replace 
the ones I have in the group now, which to say the least is a tedious process.

TIA

Graham
