>I am running CABuilder to generate a VCX file containing _CABase class and more than 100 subclasses for every table in my SQL database, but after closing the class browser (final step), the VCX and VCT files appear as "open" and I can't delete them until I close my VFP session. I can copy them to my development folder but I can't delete them from CABuilder's Classes folder.
