Issues with word wrap in Neoclassical theme

I’m using Neoclassical ( ) as the theme for my final year project and I’ve been having trouble with getting text to wrap around images. I’ve looked at the standard howtos in codex but they dont seem to make any difference, I know that you can word wrap as I’ve seen it working with the theme.

As for the coding it seems to use some kind of non standard formatting for images:

.format_text img { }

		.format_text img.left { margin: 0 10px 1.53846em 0; float: left; clear: left; }

		.format_text img.right { margin: 0 0 1.53846em 10px; float: right; clear: right; }

		.format_text img.center { display: block; margin: 0 auto 1.53846em auto; float: none; clear: both; }

		.format_text img.block { display: block; margin: 0 auto 1.53846em 0; float: none; clear: both; }

		.format_text img.frame { padding: 9px; border: 1px solid #ddd; background: #eee; }

		.format_text img.stack { clear: none !important; }

is anybody else using this theme and have you found any solutions to this problem?
