Help with MouseDown event?

Hello to everyone, I need some help with this. I have a Label which I want to add an action when I click it, but the problem is that I have added a context menu, so when I click with the right button over it activates the action too. Is there a way to only activates the action with the left click? Thanks in advance.

MouseDown activates when you press ANY mouse Button

if IsContextualClick Then .....

can then determine if it is the RIGHT button (and then you deal with you menu)
otherwise by default it is the LEFT button
