Just popping in one last official reply before full thread closure - it is true this is a known bug that happens for some users. If it is still happening to you, could you please submit a console log when the bug is active to <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> ? The bug is still being investigated and worked on, and further information is always good. You are also always welcome to contact <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> for a refund as well if that does not work for you, but the problem is being addressed.
