In Firefox 3.6.12 on XP, I run into an undesirable situation with my map markers.  It seems that google maps is alpha blending my markers slightly with the markers behind it.  It's not something in the source image.  It does this even when the markers are gifs (which don't support alpha blending but only binary transparency).

For example, here's what it looks like when you have this black E marker on top of a bunch of little red markers:

I've blown it up a little so you can see how the red markers are bleeding through the foreground marker.  This actually makes the marker less readable and I'd like to be able to turn it off in code.  Is there any way to do that that I'm missing?  I've dug through the docs and haven't found anything.

A picture doesn't help us help you at all. We need a link to a map
that shows the problem.

Yes, it DOES help, as long as you want to help rather than just be a stickler for the rules.  I do a lot of troubleshooting help, and I realize why you want to be a stickler.  But I also do enough to know when it's overkill.

Nevermind.  Just forget I asked.

It doesn't help me. Maybe it helps you. But you are the one asking
for help...

If there was a feature like I'm talking about, it WOULD help.  I have already concluded that this is a non-configurable part of the API.

If you're not going to help, that's fine and is your choice.  I asked for help, but I did not ask you to post telling me you're not going to help.

Like I said, nevermind.  I've already decided it's a limitation of the API.  I was thinking about switching to the yahoo maps api anyway.

That's too bad. It was a really interesting observation and I was king
of interested to see what was causing it.
