Opening pictures problem

[1937pickup]

I love looking at the pictures that are attached to posts. I have been having a problem opening them. When I click on the thumbnail the picture goes to the larger version with the "pinwheel" spinning. It never goes to the larger size. I need to close the picture and click on it again to get it to the bigger size. Anyone else have this problem and is there a fix. I looked in the FAQ posting and saw nothing about this problem.
