My app is taking a life of its own. I am working on picking the perfect domain for this, and when I do you can see it in action.

Here’s what it is: A mashup of Google Maps and USPS (UPS and FEDEX are the first slated improvements). It is 100% AJAXified and really quite cool. It does a number of different calculations for users, from the distance between two stops on a package’s route to the average speed between each point.

I am being held back by a problem that I am making no progress with though. In FireFox it works perfect. But IE and Safari behave the same but different from Firefox. They decide to plot the stops in a random order, which is different each time. I have yet to discover any pattern. Firefox though plots in the correct and same order each time. Has anybody heard of anything like this before?

here are some existing projects:
