Error - Error sending ARexx message - 'xxxx'

TSMorph-render or TSMorph has had a problem sending the ARexx message. ARexx may not be running, or the script may not exist or have errors.

Resolution - Ensure ARexx is running, check the scripts - See parameters PRESCRIPT, POSTSCRIPT and LOADSCRIPT, or PREVIEW - exist and have TSM as a suffix.

If the above is OK then use TCO and TS to interactively trace the script.
