Any file over 2mb in size gets a "Connection to server timed out , try again " or a "Connection to server failed ." error . This happens in IE8 and Firefox . I traced it down to Nod32 v4.0.474 . If I disable the antivirus entirely , files download normaly . Enable it , and no file over 2m will complete . I haven't changed any settings away from default . Any suggestions or is this a genuine bug ?
