Question Overlapping clicked point on a HTML image map

[psypgmr]

I am using a webbrowser control on a windows form, in VB.Net 2005. On this control I have a fairly complicated HTML image map, using javescript to place an icon where a user clicks, and pass the clicked area to the VB.Net code so it can be handled accordingly. I have figured out, with recursive code, how to place an overlapping icon over a previous one when the user clicks on a spot where a previous icon covers. What I cannot figure out is how to make the underlying map recognize the click and perform the desired processing because the previous icon covers the active area of the map. Any ideas would be greatly appreciated. Thanks!
