Detecting a mouse click in a field

[Glen Bojsza]

Hello,

I have been trying to figure out th ebest way to determine if the user
has clicked the mouse in a field.

Both mouseUp and mouseDown are for buttons (though if the user right
clicks the mouse in a field then it acts the same as a left mouse
click on a button).

I am not interested where or what the user has clicked in the field
only the fact that they have clicked in the field.

thanks,
