Kaz,
Sometimes it can take a few hours to get a response to a support question. Please be patient. We get back to all posts as quickly as we have time to do the appropriate investigation and come up with an answers.
As to your question, it seems like the z-index is wrong with our content plugin and a separate comment box. If you add the following line to your template's CSS file, it should fix the issue:
.scsocialbuttons {z-index: 99 !important;}
I've added it to our tracker to ensure that we're doing the proper z-indexing as well for the next release.
Thanks,
Alex
