Once you're in a crosswalk with the light, you have the right of way. The driver has to yield; it's the law.
The timer at that intersection is off if you have the signal only a few seconds. A call to the traffic division of city hall should take care of that.
In the old days, if a driver cut me off in the intersection, I'd plant my foot into their rear quarter panel. Only once did a driver stop, and I got right back in his face when he got out and came at me: "Hey, you: I was in the cross walk and I'm in the right of way, and you know it. You gonna take a swing at me and add buttault to a simple traffic violation? I have your plate number and your description. After you get outta jail I'll sue your arse!" He just called me some names and then split.
I'm not a small guy and I'm in good shape; that may have something to do with it.
Then again, there are those who eschew crosswalks and lights, then smirk at you daring you to hit them. I just yell at them: "If I had a cowcatcher on my front bumper you wouldn't be smiling" or "My car weighs more than your head, fool--but not by much!"

This isn't a problem in Canada; at least not the places I've been. Pedestrians and drivers alike mind and respect the crosswalks.
