Is there a compatibility issue w/ vB and FF 3.5? One of our users wrote this:

Re: Firefox 3.5 is released
My only issue, and I'm not sure of the cause, is that since installing 3.5, I haven't been able to properly use the quick reply box on this forum. Normal reply works fine, but the quick reply always tells me that the message is too short (regardless of how much is written).
