Differences in Webviewer between Windows and OSX

[Dave-o]

Hi all... I've used this forum a lot as a resource in learning Filemaker, but this is the first time I haven't been able to resolve a question simply by searching.

I'm using a webviewer in Filemaker 8/9 to utilize google's geomapping features: we take an address, use the google maps api to determine a latitude and longitude, and generate a map with a pinpoint and description at the address.

This works fine under OS X, but under Windows none of the pinpoints show up. If I open up the url that the webviewer is using with Internet Explorer I get the same problem. Using Firefox and Safari, everything works like a charm. Does the Windows version of Filemaker use IE as a base for it's webviewer? And if so, is there a way to change this?

Pulling my hair out,

Dave
