[interchange-cvs] interchange - jon modified code/UserTag/button.tag

User:      jon

Modified:  code/UserTag button.tag
Log:
Make sure that the current button being pressed is the only one whose
mv_click_map_* variable gets set.

This works around the problem of a user clicking one button, using the
browser's Back button, then clicking on a different button, and both
mv_clicks execute instead of just the most recent one.
