I know you guys are stumped (so far) why the AG tray icon's context menu appears on my second monitor. Perhaps this info will help. I run at 120 dpi on both monitors. The context menu on my second monitor is placed on the first 25% of the screen. Now if you do the math you will see that a dpi of 120 is 25% more than the default dpi of 96. Perhaps you are placing the context menu based on dpi and assuming my monitor is wider than it actually is? Running at 96 dpi places the context menu correctly. Just a thought.
