I replaced the light fixture over my bathroom sink with a flourescent. The problem I am having is sometimes when I flick the switch the bulbs start to energize and then stops. I have to run my hands over the fixture to remove the built up static electricity (or so I think), wait a few seconds and then flick the switch. The light will then come on. I know I grounded the fixture the right way. What can I do to fix this problem? It's more of a pain then anything.
