I have noticed that when I hover over the designer's main window when previewing on the task bar, it shows previously opened dataset editor windows. I cant open these obviously. ![16995548680558574252641111052863](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/6/c697902d7db3ee7c6065dcfa3aa5636f549a511d.jpeg) I have also noticed my designer memory usage slowly creeps up and if left open long enough (i tend to not close the designer when leaving for the day) it will crash. Possible memory leak? ---

If you go to File -\> Open and reopen the same project again, do those windows go away? ---

Yes, they do disappear.
