Open the sim to any screen.\r\n2. First slide the Mass 1 mass slider all the way to a max or min.\r\n3. Then slide the Mass 1 length slider all the way to a max or min. Whether you pick max or min, it doesn't have to match your decision in the previous step.\r\n4. Now sliding the mass slider around will cause the left part of the Gravity panel, the left part of the return button, and the single mass button to disappear.\r\n\r\nNote that these only disappear if the mass slider is not at a max or min. Once the slider is returned to those positions the issue is not apparent. This gets more complicated to explain when the Mass 2 sliders are made visible as well, but the issue does still happen.\r\n\r\n![pendulumlabcroppedpanel](https://cloud.githubusercontent.com/assets/5863899/12928751/8739085e-cf2c-11e5-8769-406f5a3756bd.PNG)\r\n\r\nTested on two personal Win 10 computers to verify it's not a hardware issue.
