Since the 5.5 update we encounter a problem in the recent and random photo addons. These are showing perfect, and are nicely collapsable. But there is a bug wich happens if you collapse them, navigate away from the page, and return to the main page. This is what happens:
In IE the collapse image is missing (see screenshot), but you can still collapse them. In FireFox the image is missing and it is not collapsable anymore. Also on Mac browsers this problem is happening.
We run vb3.6 + pp5.5. The problem is occuring in all templates that we use (also in the default vb3 template)
