As noted above, there is a shortcoming in VFS where it doesn't know how to find CEL's vfs.cfg fragment when installed. Presently, CEL programs which depend upon CEL's vfs.cfg will work correctly only when CEL's vfs.cfg is in the "current working directory".
i have set working directory in VC++ to CEL (where my cel vfs.cfg is) and i got the same problem:
cel.persistence: Error opening file 'basic_level.xml'!
celtest: Error loading level 'basic_level.xml' at '/cellib/lev'!
should i merge CS and CEL vfs.cfg files ??
