Bug: VE4 and FF 1.0 pushpins offset wrong
I know firefox 1.0 is old, and hopefully most users have upgraded, but we still need to support the absolute widest range of browsers found in the wild.
I upgraded my mapping to use VE4, and found the position of custom pushpins was being offset incorrectly. I'm pretty sure it used to work correctly in VE3, as I would have noticed it.
To repro the problem look at:

In FF 1.0, and notice how the pushpin popup is offset. It's fine in Firefox 2.0 and IE 6/7.
