[Loadstone] OSM files?

[Colin McDonald]

hopefully this is on topic.
when i try to export a map from the OSM website in xml format, it seems to 
be exporting, but gives me a 400 bad request  error and doesn't bring up a 
save dialog or anything.
Is this perhaps an issue with the specific map i'm trying to export, or is 
it a common issue with the OSM export tool?
or perhaps i am doing something wrong.
thanks
regards
Colin
