No feedback after submitting to gallery; No images showing up under "Submitted images"

I tried to submit to the gallery an image I already had uploaded. First I had to verify my e-mail (no problems there). Next I went to submit the image again and after clicking save on the "Is this title okay?" prompt all I see is a very tiny box with an 'x' in the center of my screen. The rest of the screen fades slightly as if it were displaying a linked image in the comments, but no other feedback.  Not sure if I am missing something, but it appears I am unable to submit anything to the gallery at this point.
