So.... I'm working on a context sensitive rose command menu. You right click and you get a bunch of options that you can select. The idea behind the menu is for advanced commands in a tactical strategy game. I'm trying to make it context sensitive so that a user can right click an enemy unit and get specific advanced commands for that unit.. or click an objective and get specific advanced commands for that as well.

The problem I'm currently having is that the code to determine what is hit isn't coming from the center of the rose menu, where the user hit the right mouse button. Its coming from where the user is left clicking to click the command button.

Not sure if I explained that very well... but regardless of where I right click I'm getting the terrain...and only when I left click do I actually pick up objects.
