Does it now supports multiple currencies.???
It should, but I admit this feature is not heavily tested (I only use USD). Give it a shot, if it breaks somewhere let me know and I can fix it.
The OTHER_IMAGE_ARROW_SOUTH_EAST definition mark seem to be a missing one from the extra_datafiles folder - which might be the reason why you're experiencing difficulties with this definition name.

I searched for it, from all over the MOD, as only one results showed up - line: 743 from admin/orders.php file. A slight bug I might add.
Yes that's a whoopsies on my part. Darn Firefox hides broken images, so it slipped my mind. Correction has been made to the file.

If you don't want to download again, just open admin/super_orders.php, find the define, and change this...
Code:
zen_image(DIR_WS_IMAGES . OTHER_IMAGE_ARROW_SOUTH_EAST)
To read as this...
Code:
zen_image(DIR_WS_IMAGES . 'arrow_south_east.gif')
