Right. When I wrote the driver interface orientation code, I originally held orientation to integer values. But then I realized, why not have some fun and make it more general. The shear problem showed up right away, and having (over) filled my capacity for "fun" projects at the time :), I left it at that. -- Maurice LeBrun ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
