Employee hover contactmenu doesn't work in Safari 5.1.7 on Windows

Hi there Team Enfold!

I recently installed Enfold on a WordPress site and it looks spanking!
One minor setback though: the client for whom I’m managing the site noticed the hovers on the team photos don’t work in Safari. What’s quirky though, is that the hover does seem to work in Safari before the page is completely loaded. Before the page is done loading, I hover my cursor on the image of the employee, and the contact menu does appear. Then, after the page is fully loaded, I move away and hover again, and nothing happens.
I tested several CSS solutions (display block on several elements, z-index constructions), but none seem to work.

Do you have any idea what it could be?

Thanks in advance.
