Has anyone used the .NEt V2 Image Map class before?

Supposedly, its somehow possible to set a "z-index" for overlapping HotSpots( ) yet I cant seem to find out how as no one in the world appears to have done it before.

Ive tried overriding the Render method in ImageMap to intercept the output and then inserting style=z-index:*A NUMBER*; but this has does not actually work.  The style writes out ok, but it makes no difference to which is on top.

Anyone?

I guess if someone knows how to do this in standard HTML thatll do nicely as well as Ill just butcher MS code.

Thats not looking like a dynamic solution to me.  Im creating all my images and image maps dynamically.  There can potentially be hundreds on the screen.

So far Ive established that the first created HotSpot/ is the one that is the "highest" on the webpage.  I might just need to reverse the order in which Im creating them or create them another way.
