In using the xmlbooks demo with the new builds, the Synopsis block is rendered behind the background of the Book block thereby making it invisible except for one little block indicating the lower scrollbar. Attempting to scroll using this causes a crash.

and the url is...?

This is the demo posted on the mozilla.org site. It's a zip file that you must download and use locally: http://www.mozilla.org/newlayout/demo/xml/xmlbooks.zip

troy, you'll be proud. i actually researched this one before passing the buck. there is no longer the crash that was originally reported, but there are definitely painting problems and it's because the window hierarchy is busted. the frames look correct, as do the views, but below the root scroll frame (and it's clip view) all other windows are siblings of each other instead of there being six trees. kipp thinks this might be related to the frame construction changes. use spy++ to look at the window hierarchy and you'll see what i mean. i have a simpler example that i can send you if you want it.

Looks fine to me. Marked verified fixed (viewer.exe, 09-march build).
