Anyone encountered this mild annoyance?

Hi all!

Picture speaks a thousand words (and I don't know the right technical terms for stuff) so take a look :)

When I accidentally hover the mouse above "community" and it opens that black strip under it (that has "community" and "blog"), it sometimes (not always) freezes there, covering the video, and I can't get it to go away. I tried re-hovering over the same place, left-clicking anywhere on the page (except links because I don't want to leave the page), scroll down and back up... still there.

I wonder if the issue is specific to me (caused by my mouse, comp etc, in which case, never mind :)), or did other Blenders notice this too?
