Question: I have the xfbml version of the like box on one of my sites. All the settings should be correct. The problem is that according to a customer, the comment box does not show up after clicking "like" on Safari (Mac). To be more precise, the actual claim is that after clicking like, she cannot click on the first 3 images in a gallery. An example of a gallery can be found here: REDACTED

What I gather is that the comment box is created, but does not become visible. I have tested this with every browser available to me and cannot replicate the issue. 

Has anyone heard of a similar issue or has an idea about what could cause such behavior? A bonus would be if someone with the latest build of Safari on Mac could try and replicate the issue.

edit: To any who might happen upon this question and have the same problem, the solution was to update the Facebook SDK loading script, as pointed out by others below.

Answer: 
We have had same problem. In our case, Facebook API initialization script was loaded statically, which caused the problem (somebody downloaded the script and included it into web application). After change to standard dynamic initialization in compliance with [facebook manual](http://developers.facebook.com/docs/reference/javascript/), problem was solved.
This is a known Facebook bug:

Basically, one gets this behavior if secure browsing is enabled on the Facebook user's account.
