[jawsscripts] Re: hairy problem on a project, re differing coordinates yielded in terminal emulation installations

Had a similar situation more than once. The font could definitely throw 
your coordinates off. Have you checked options in the Client Access 
configuration files like toolbar size, cursor type and rule-line? If you 
don't already have it, you might find useful information in IBM Client 
Access.pdf. There's a copy at:

Good luck,

Mike
