I've installed latest DNN 7 CTP on Windows 7 x32 virtual machine with SQL Server 2008 R2 Express and IIS 7.0. Looks great, indeed!..
But, I could not see any module actions menu - there are no semi-transparent "Manage" button in / near module header (like one in DNN 6). So, I could not edit HTML module content or manage another module.
"Create new module" dialog in a control panel also not working - then I select it, area is expanded down, but then it not filled up with controls, like Module Name, etc.
Since there are no "Manage" button in Extensions module too, I've uploaded and installed new module through Host > Host Settings > Upload Skin / Container (not very clear way).
Maybe, I expirience a configuration problem - related to AJAX, IIS7 or some other components?.. Or it is just CTP-related things?
