8299 installation problem

Newbie

I've installed an 8299 in a bathroom in a 90 year old house, 2-wire, ungrounded. The light switch works normally, but when the lightswitch is off, testing and resetting the GFCI causes the receptacle to trip and the light to flash about 10 times per second. Oddly, this only happens 9 out of 10 times that I try it - 1 time out of 10, it resets normally.
