My fault there.  I simply copied the metafile and
sized it in a WP before exporting to PDF.

I agree.  It seems to work perfectly with R-2.4.0
Patched. I had not realized that there was a Patch
version out already  but as soon, as I upgraded, the
gantt looked fine.  However one serous complaint :
Kane not cane!!!!

Thanks a lot.  This saves a lot of time and trouble.
