That's the program I use and I love it. Free and powerfull. Yawcam can also show the outside link so it's easy to copy and past it into a web page. I guess you have a web module that post your aquarium info? what contrôleur is it?

I have my webcam setup, post all my aquarium info from my controller, and the site is locked. Piece of mind while I sit here at work wondering if my updated arduino program is actually going to turn on my lights in 2 hours *fingers crossed* haha.

As for the actual problem on the GFCI, that's a weird one. GFCI has to have "leaking" power to trip, so something is either shorting to ground, there is too much inductance/capacitance in the circuit. Also, is it a GFCI Breaker? or outlet? An outlet doesn't protect against over-current, so that could help eliminate the overloading issue if that's the case. Also, are you plugged into a surge protector? that could be the problem as well since cheap ones can shunt power surges to ground causing the GFCI to trip. A highly inductive load like the transformer being energized can cause power surges that may do this.
