It looks as thought there is a missing delimiter in the path name.

Do you have an R:\bb\ folder?

When you set the name, is it possible to enter: 'R:\bb\' instead of 'R:\bb' (manually include the trailing backslash).

If their code does not check for or call the IncludeTrailingPathDelimiter function, it may cause exactly what you have witnessed.
