I created a branch from the trunk using Tortoise SVN - Branch/tag and checked switch working copy to new branch/tag. Everything worked fine.
Now I would like to make a new branch from the trunk, and when I click Tortoise SVN - Branch/tag, the Repository From WC / URL: (the part that you can NOT change from this dialog box) is set to my other branch, the one that is now my working copy.
What do I need to do to create a new branch from the trunk? Can I switch the working copy back to the trunk? If so, how do I do this? I have searched everywhere for straightforward instructions on this and have found nothing.
