When I edit a post which is a PhotoQ post I get an error warning in IE at the bottom left of the screen:
HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)
I did some searching and found this article:

Which seems to point to the fact of a problem in the HTML code. This is only a problem in IE but I think it's probably easy to fix, with a small change in the code... I am about to start investigating a fix, but thought I would post here first, in case anyone has a solution already.
By the way I made a clean install of WordPress to confirm that it was not due to a clash with another plugin...
