Firefly sims & Lectora launch page

This could very well be a Firefly issue (I have a support call into them) but I wanted to check with the Lectora community.I have Firefly sims launched from Lectora pages. When a sim has finished, control is returned to the Lectora page. The user then clicks on a Next button to advance to the next Lectora page. Sometimes, however, (and it seems with increasing regularity), when control is given back to the Lectora page and before the user has a chance to click Next, the sim will re-launch. It's almost like Lectora is storing up calls to the sim in a queue (perhaps from where a user double-clicked on the launch icon repeatedly before the sim actually gets executed) and the call to launch gets re-executed.Any ideas?
