Confilct with DD_belatedPNG and IE6

coalescent

I don't know if such a specific conflict will be addressed but I thought it would be worth pointing out. When using dataTables 1.7.5, the latest version of DD_belatedPNG (.8a) and IE 6 with a background png in any dataTables initialized th cell (which DD is trying to fix), IE6 crashes.

We've worked around this by using a seperate gif sprite file for IE6 so haven't investigated in more detail but can confirm the behaviour with this combination of items.
