I have made several galleries and there seems to be a problem each time. For some reason, clicking on a thumbnail image causes the gallery to collapse altogether! Here is an example: carolinedooley.com/griswold-gall.html
All of the photos work, but randomly, one will cause the whole gallery to collapse. It is not always the same image that will cause the problem.
I just realized that this problem was reported last week. For some reason, it is labeled "Does not need an answer". I am reposting because I think this DOES need and answer. Others are also experiencing this...
