I have installed DW CS6 on my PC (Windows 7, Internet Explorer 64 bit) and have also invested in the Adobe "Classroom in a Book CS6" book. I installed the DVD that came with the book and began with lesson 1. However, the first screen on lesson 1 appears without any DW toolbars at all, making it impossible to navigate in any way through the tutorial. Is this a compatibility/security problem with Microsoft? I've tried turning off pop-up blocker etc etc but am getting nowhere. Any ideas?
