Right click causing behaviors on slide without right click triggers

Hello all, 

I have an odd one. We use scrolling panels heavily in our Storyline projects as we mimic Salesforce so that our learners can practice using that tool. One slide is generally a large scrolling panel with a recreation of a Salesforce page. We often put hotspots in the background to give the learners feedback when they select the incorrect area of the tool. The triggers associated with those hotspots are generally on a "When the user clicks" trigger. However, we just noticed that when users right click on those hotspots, the screen will jump back up to the top of the hotspots. We have no right-click triggers associated with those hotspots or anything else on the slide. But, on every simulation, a right click on the hotspot will jump the slide back up to the top of the hotspot the learner right clicked. This is all happening within the large scrolling panel. I am not sure how to stop this from happening, as there are absolutely no right-click triggers associated with the slide at all. Has anyone else experienced this? Any thoughts?

Thanks for any help!
