Why is the SDMB trying to run Quicktime each time I open a thread?

I’m using IE 7.0, so there may be a bug of some kind that they haven’t ironed out yet, but every thread I open gives me the following message on a yellow bar at the top of the window:

So what’s the deal?

It’s not coming from us; we have no QuickTime content on the board.

Never mind, I think I fixed it. Apparently there was an add-on that was trying to run something. I disabled it and the message isn’t coming up anymore. You can close this if you want.
