We seem to have an intermittent problem with image popups. We have an image style that has been formatted (before my time) to have the image smaller (larger than a thumbnail really) when you first look at it, but you can click it to make it pop-up larger. However, sometimes in the output, instead of popping up the image larger, the pop-up frame displays a 'null' error. There doesn't seem to be any consistency as to when this happens. I've checked all three of the major browsers and it works fine for me. But apparently some end users are experiencing this.
Anybody else out there whose seen this and might have a remedy? Is it a browser rendering issue? Could it have anything to do with how the product loads the help?
Thanks!
