Thanks for the info. The speed boost is great and I will gladly trade a
bit of screen flashing for it!
By the way, when I did the build as per www.mozilla.org/build/mac.html I
ran into one problem that wasn't mentioned and was a little tricky to
resolve. The build failed while linking _NSStdLib.mcp as some symbols
didn't get resolved. It turns out that the real failure occurred a few
projects back in _Interface.mcp when it was linking in the
ContextualMenu library. It looks like CW didn't like the fact that
there were two PEF containers in the library (68k, PPC) and so wrote out
a truncated InterfaceLib. I sliced and diced the ContextualMenu lib up
and things were fine.
Assuming my situation is not atypical, perhaps a note should be made in
the build instructions.
