Individual product pages work fine under any conditions until I install Image Handler. At that point a blank page is served up. No errors, no source code.

Can someone confirm that Image Handler is working with the most recent version of Zen-Cart? We've never had these issues before.
I just discovered the issue:

Admin > Configuration > Product Info > Previous Next - Navigation Bar Position

This needs to be set to 0 (off). Otherwise Image Handler displays a blank page. Anyone know why?
