The website it internal to my company, so you won't be able to click or test. I'm hoping my description helps and maybe someone has heard of the issue, or at least maybe has some conjecture as to what might be causing it. But the issue never happens on IE, only Chrome. I don't have Firefox and cannot install since it's a work PC that's largely on lock-down by IT dept, in regards to adding software.
