Lobby: Problem importing GPX files

I recently started having problems importing GPX files (exported from MotionBased). Everything seems fine until I hit the "Import" button, after which I get the world map view then it quickly changes to a map of my default address. This started happening last week. Again, never had this before. Have tried IE and Firefox in Vista and Safari and Firefox in OS X. Same on each. (The problem I used to have was a timing out of the script that required me to keep hitting a "continue" button to make sure it went to the end.)
