I picked up that it's flash from several comments, I wasn't intending to say it's a bug with XF, I guess just venting frustration. It seems to me that if this were a common issue and causing crashing left and right, they'd friggin fix it.
So now my question is (and this may have already been answered in multiple places, sorry....) what is flash needed for, and am I "missing out" on some "experience" on XF sites by disabling it?
