I'm no electrician, but...

I'm beginning to think we have an electrical problem. When I got home today, I flipped on the light switch in the hallway, saw a bright flash of light, and the lights went out. It turned out that a light bulb burning out actually flipped the circuit breaker. Unbelievable. Either those are some seriously high-powered track lights, or we need to do some rewiring. I wonder if it's a problem that the whole condo is on 2 circuits?? We've known about this since shortly after moving in, but we've only had problems when trying to run the washer and jacuzzi tub at the same time. Or a bathroom fan and a vacuum cleaner. I think I'll put this on my "think about fixing it eventually" list. Along with about a thousand other things.
