Bridge CS3 & ACR with dual monitors

Question: In a dual-monitor Windows XP setup, how do I control which monitor ACR opens on when opened from Bridge?

Background: In my workflow, I use Bridge to open small batches of DNGs in ACR. What I want is to have Bridge on monitor #2 (uncalibrated), but have ACR open on monitor #1 (calibrated). At first I had Bridge opening on #1 and couldn't get ACR to open on #2. Then I figured out how to move ACR to #2, but now it always opens on #2, regardless of where Bridge is. How to fix?

Thanks,

Andrew
