Problem creating a branch

I'm trying to create a branch from a modified working copy. The first
screen shot is the Copy dialog I used. The second screen shot is the
result. BillingMilestoneSummary.cs and CaseDataContext.cs are both
existing versioned files that have been modified in the working copy. The
branches folder in the repo is empty.

I'm new to Subversion/Tortoise, so I'm not even sure that what I am doing
even makes sense. I made some changes in my working copy and then decided
to create a separate branch for the changes because I don't want to commit
them to the trunk yet.

I'm running on XP SP3. The repo is on Windows 2003 Server - it's a
vanilla installation of VisualSVN Server 1.5.2.

Thanks in advance for any assistance.

Mike
