VisualSVN is comitting sln file to wrong location

[Jody Breshears]

I am having a very serious problem with Visual SVN.  I have a
repository which looks roughly like this:

root
  -trunk
    -Marketing
      -Project1
        -Branches
        -Tag
        -Trunk
          -Project1.sln
          [other Project1 files and folders]
      -Project2
        -Branches
        -Tag
        -Trunk
          -Project2.sln
          [other Project1 files and folders]

My local working copy starts at "Marketing" and mirrors the repository
structure thereafter.

When I attempt to commit Project2 using VisualSVN at the solution
level, it acts as though I were committing at he "Marketing" level, 2
levels above where I am. This results in the commit picking up files
Project1 as well, which is a problem.
This does not happen if I commit Project2.sln directly from Tortoise,
nor does it happen if I use VisualSVN to commit at any level lower
than the solution.  The same thing happens with Project1 (or any other
project in the structure.)

I have run cleanup, and I have deleted Project2 and done an update at
the "Marketing" level, to no avail.  I am at TortoiseSVN 1.5.9, Build
15518 and VisualSVN 1.6.2.

Any help would be appreciated.

Thanks,
  Jody
