	Here's a simple method if you have a little extra memory.

 	Use a background buffer to draw a mirror image of the displayed
hex grid only use one color per hex. Then when the mouse is clicked 
pick up the color on the background buffer thats at the same x,y as your
mouse and thats your hex location. You could also use variations on this
to just fine tune aproximations. eg narrow it down to 5 hexes and then use 
the back buffer to get the exact hex..
