Hi Dr Van Hauten,  Sorry I missed your report. Are you still having this problem? I am unable to duplicate the behavior here. If it is intermittent, it might be very difficult to track down or fix, but here are some Troubleshooting steps you might try to alleviate it. If you can get it to happen reasonably consistently on a supported browser, I'll see if I can escalate this.   Could you please carefully work through these steps of our guide to   Solving Technical Issues  ?        Step 1: Make sure to use the right browser   Please check if these issues persist when using both Chrome  and  Firefox.       Step 2: Ensure that there are no extensions/addons interfering with Roll20   Please disable  all  add-ons/extensions  and  anti-virus programs.       Step 3: Clear your cache      If none of the above succeeds, please thoroughly work through   Step 4  .   (Don't forget the complete Console Log!)    Thank you!
