Anyway, when he ran into the 'wrong version of Tortoise' error in H+M, he quit trying. Unfortunately, this was after we had gone through the steps of settin up SVN in H+M via the SVN options under the File menu.
We have since decided that manual version control using up-to-date SVN and Tortoise is the right procedure.
However, we still get this in the right-hand column of H+M 8:
I've searched through the H+M 8 help file, but can't find how to un-set up SVN. How do we let H+M 8 know that it can relax, we aren't going to exploit the in-built SVN capability in H+M?(folder & project name) is under SVN version control. The newer Tortoise SVN client installed on your system requires the additional installation of the Collabnet SVN command line client. This Collabnet client must have the same version number as your version of Tortoise for Help+Manual to be able to interact with the SVN system correctly.
In other words, we need a button that says, in effect, "Forget SVN."
