Flash caching is exceptionally aggressive, and annoying. For development purposes you can try appending ?12345 (or whatever) to the URL to trick Flash into thinking it's a different URL. If I get a minute next week or so, I'll add a (FlashVars-configurable) option to Potlatch to tell it to use POST requests instead, which is a better way of defeating Flash's caching.

But whenever I try that, I get the error "You don't have permission to open a file...". If I copy the URL into the browser, it opens the file just fine and shows the contents. Is this a known bug? Am I doing something wrong?

You're not - afraid that's another Flash annoyance. :( Flash Player won't load external data from another domain unless that domain has a crossdomain.xml file giving explicit permission. If you want to load from OSM, try www.openstreetmap.org/api/0.6/gpx/<id>/data.xml - Tom fixed that yesterday so it'll work with P2.
