Path problems with my lisp routines

#1
I've used several lisp programs for many years. In evaluating IntelliCAD, I'm finding that the program will load the lisp programs but is unable to find the support files located in the same directory as the lisp programs. I have added those directories to my support file paths. The programs both use *.dcl files in order to run. For some reason, IntelliCAD can't "see" the files even though they're located in an identified support path and the same directory as the program lisp files.

Am I missing something or is there a fix for this? Thank you. I will be happy to send the zip files containing these programs if needed.
