Ah. You need to be an administrator to look at the system directories? 
[I'm also on Win7].

I didn't look closely enough; only the junctions in system folders are 
failing for me with an exception. The junctions in my user directory are 
not. I do hope I haven't wasted too much of your time in not describing 
the problem correctly.

I realise there are differences between junctions and symlinks at the 
ntfs level, but the only things that seem relevant to the application 
are that junctions are limited to directories on a local volume. So I 
consider junctions to be a subset of symlinks. Regardless, any reliable 
indication that a directory is a junction would be useful, and the hack 
I've been using thus far appeared to work for all the junctions on my 
system.

Yes, I'm ashamed, I did know that but missed it from the example.

Many thanks.
