Another three way wiring question

I just installed a new light fixture in my dining room that is controlled by a three way switch. The wiring at the fixture just had the three wires - black/white/ground. I simply connected the three wires to the new fixture and thought I was done. I did not touch the light switch wiring at all.

However, when I turned the power back on, the three-way no longer works properly.

Switch A, when in the down position, turns the light on. Switch B will now work to turn the light on and off.

Switch A, when in the up position, turns the light off.
Switch B, does not work at all when switch A is up.

Switch A also has a dimmer, which doesn't work with the new fixture.

Where did I go wrong? What can I do to fix this?
