[Xerte] event failing on second call

[Dave Burnett]

I click a button to pop up a scrolling text window which is populated with a loadVars call to a text file.
rootIcon.loadVars('http://www.myserver.com/common/revisions.txt?nt=' + (new Date()).getTime());
followed by an Event interaction
onLoadVarsrootIcon

It works the first time, but if I click the button again, the event will not fire again.I ran into this once before but can't remember what the issue was.
