Thank you Al - I LOVE and own so many of your products. Project Seven is terrific!!!
And to Rik Ramsey - I did read all the thread and did search for background-color. Until the reset issue was also cited as the problem, I was not able to identify the issue, especially when all the past versions including 5.5 which I were fine. This is still an issue DW needs to fix and it is a bug. So breath was not wasted and frustration is reasonable.
I don't know if this will help others with this bug, but here goes...
I just bought CS6 to edit a website on a PC (it was originally built on a Mac, and not in DW). Had the same problem of a completely white Design window in Split or Design view which was very frustrating.
By chance I found that if I just double-clicked in the white space of the Design window that a working Design view appeared (had to slide over to the right to see it fully) and I was able to start work on the site. Phew!
I'd like to know if anyone who is experiencing this bug can reproduce the effect?
The fact that a double click on Design view revealed additional content indicates that the outer element has an overflow:hidden style applied to it and is therefore hiding its contents from view until you tell DW to show those contents by double clicking. This is an intended feature of Design view, since if Design view always showed content that was to be hidden (as in a scrolling text area, where content is hidden below the bottom of a fixed-height content region with a scrollbar), then any layout would be unexpectedly and adversely affected by that unintended extra content.
Gary you are a lifesaver! This new bug in DW is so annoying but even more annoying is when someone asks a question and people have to leave know-it-all responses or links to places where other people have posted the problem, instead of actually trying to help with a constructive answer! So thank you! The hint about the Eric Meyer reset was just what I needed!
