One of our visitors has reported the following behavior when accessing our forum ( 179154 ):
I haven't noticed a specific ad that's up when it happens, but I will get a box that says it is trying to open an Adobe Acrobat/Reader Application and when I press cancel, that tab freezes. About 5-10 minutes later, a bar pops up on top saying something to the effect that IE has stopped a website from downloading files to my computer.
I can't seem to reproduce the problem, even when I stoop to using IE. ;)
