Ok, I tested your Waterfront tour in the following browsers:
Internet Explorer = Yes
Safari = Yes
Opera = Yes
Firefox = Yes
Chrome = No
Did you download the very latest build of Tourweaver 7.0?
Did you go to the "resource" folder in the program install directory and get a "copy" of the TWViewer.swf file?
You need to get this file and uplaod it to the "root" directory of your Waterfront tour replacing the existing version.
If the tour was built with TW 7.0 it is a straight swap. If the tour was built with TW 6.5 you must rename it to all lower case twviewer.swf to match that of the original.
The original 6.5 twveiwer.swf is sized at 236kb and the TW 7.0 replacement is sized at 354kb
You MUST clear your browser cache before the new version will work.
All that said, the Google Chrome browser is the ONLY browser your tours are not working with (until you swap the twviewer.swf file) I'm not sure how popular Chrome is as a browser? It doesn't rate very high in Australia. Still, all should work and this is one of the downfalls of an integrated Flash player that is builds behind all other browsers.
