Not sure if this will help, but here are my thoughts...

Several workspaces are running successfully on XP Pro SP2 but on one of them I am getting a problem. |
DBG works with your
project, not
workspace. If your workspace has more than one project, check that the project you are trying to debug is indeed set as the
active project.

The workspace which is causing the trouble is debugging MODx code |
To be sure it nothing to do with MODx, I suggest you create a simple script of your own in the project and see if you can debug it.
