I ran into this last night; but it wasn't all source files, just the
ones I had copied.  I even tried moving them into directories without
strange characters, and even back to the same source drive, but still
couldn't get the property pages.   But only on the souce files that
were .cpp the originals were .c and worked fine.  (A large portion of
sources I copy from .c to .cpp so I can build as both C and C++
seperately).  All of the .cpp files would not let me bring up
properties.  I manually copied one of the files and added that to the
++ project, and was able to bring up properties.  I was unable to
track down what exactly the problem was with the other sources.  They
were exactly like the .cpp that I had manually copied but they would
not allow me to open property pages.  This is 2.8.6-rc2.
