Hi Lee and Tempestlight,
The problem of Ipad 2 cubic line issue is fixing by our developers.Thank for your feedback.
For publish Flash/HTML5 tour issue, we add some new features about HTML5 tour but other parts are same.For iPad and iPhone,the viewer also can be resized to fit the iPad or iPhone as tw6.5 according to our developer.However,if you want to make it more suitable for iPad ,they suggest you make 3 different skin. We delete GoogleMap settings in the default toorbar,because you can have a button to control the map viewer and you can aslo customized the size of scene viewer instead of tw6.5 "default full screen for every HTML5 tour".
I suggest you try "Scale to Browser Window" when you build a new project.
