There seems to be some confusion here about the ability of
WP 3.5e for the Mac (the one in the Sheepshaver download
created by John R.) and other WP versions.
Files created in WPMac 3.5e's native format can NOT be opened
by ANY other version of WordPerfect. You can set 3.5e to save
by default in WPMac 3 format, and files in that format CAN be
opened by WP for Windows (any recent version) or WP 6.x for
Files created by WPDOS or WP for Windows can be opened in
3.5e if the required converter files are present in the WPMac
setup (as they are in John's Sheepshaver download) AND if
John's Conversion Droplets are installed and used for opening
the files. John's Conversions Droplets are available here in the
Yahoo group, under Files > Conversions (follow the links on
the left of the browser window when you visit the group).
