Ok - I've got an animated theme for the 8300 curve.
Its 17 screens with a small animated area in the middle - all the screens are the correct size (320x240).

I followed the themebuilder/composer animated theme tutorial (on this page), but I get the following happen;

I get an unanimated background, but I get another copy of the background that DOES animate over the top of it - but the topleft corner of it is in the middle of the screen.

How do I get this centred? I've gone to the canvas size in Composer, and the screen size is set correctly.

Its ok - I sorted it out
