No problems on Safari on the Mac. But I did get an error with Firefox (some old version) on Windows. I had forgotten about that since I mostly use the Mac now, but yes I have seen this before. But it's slightly different than you describe. The message in the alert box says
Could not load GPX document [object MozURLProperty]
There is an OK button in the box that must be clicked but the map does completely load. And yes, the whole map page gets sort of a blue tint until you click the OK button.
I have a Windows 7 tablet that I very rarely use but it has Chrome on it. I couldn't get the site to work properly at all on that tablet, when I opened this thread I couldn't scroll the page. Weird. It's an old version of Chrome and I have only used it when I need to download software, etc.
