We recently loaded Win 7 x64 & SWX 2010 3.1 X64 on my machine. Loading small asemblies & drawings works great. As soon as I try to load a large assembly, it wants to load every assembly withing the large assembly in a seperate window. Even when I try to load just the drawing of that same assembly, it does the same thing. It was up to 1 1/2 hr and I shut it down. What can I do to get these to load faster? I am using large assembly mode & lightweight.
