and add your location hard discs into globalsecurity settings panel to have a test again.
*after loading the speed of scene is to fast even i turn the speed into 2
Could you please tell me the concrete builder No. of your Tourweaver? I test the speed settings in Tourweaver7.50 and it works well.

Please replace the player in installer, then the issue would be fixed. The player can be downloaded athttp://gallery.easypano.com/test/Jack/replace-installer-file/twviewer.zip
*when i activate fullscreen, my screen is turn to blank white
I try to view your tour in full screen with Chrome and IE9 and both work well. Please update your browser and flash player to the latest to have a try again. If the issue persists, please tell the edition of your browser and flash player.
*i can zoomin/zoomout using mouse wheel on small screen
To be honest, I am not quite understand this question. To zoom in/zoom out using mouse wheel in small screen is supported and I can also zoom in/out the tour in full screen.
