The first thing to do when experiencing “ANY” issue is to try a different viewer to see if the problem persists using another viewer. While the viewers share common code, All viewers are not created equally. Each viewer development team makes their own “Tweaks” and other changes and often times you will find simply by using a different viewer your problem is solved.  If changing the viewer did not help.. please submit a support ticket detailing your issue and we’ll be happy to help.
