Has anyone else noticed a big in Firefox where, when you press close/resize/minimise the button just starts flickering and doesn't respond to the click? A quick Google search shows I'm not the only one with the problem but I was wondering is it happening to anyone on here and if so what version of FF/Windows are you using (I think this only happens with Aero so Vista/7)? I'm on 7 with the latest version of FF currently available, 3.5.5.
