Moving objects horizontally or vertically inexplicably causes them to change their dimensions

Hello Laura, 

Sorry to hear that you ran into this issue. 

I tried replicating the behavior on my end using a same sized shape, but moving the object didn't increase its size for me. 

Since the issue appears to be specific to your installation, please try doing a repair of Storyline 360 to see if this helps. 

• Storyline 360: How to Fix Unexpected or Erratic Behavior

You'll also want to make sure that you're working locally when making edits to your course. If the issue persists after doing the repair, open a case with our support team here for further assistance. 

Let us know how it goes!
