At http://en.wikipedia.org/wiki/Lepton with Firefox, IE, and my IPAD, lines are missing on the Feynman diagram for the W+ weak interaction (the middle diagram). Also for my IPAD lines are missing on the Feynman diagram for the Lepton-photon interaction. Seems strange. Thanks.
All lines are appearing today. Please delete this report. Thanks.
Glad it works for you again. :)
