I know this might be a bit out of the scope of this forum, but I figured that this was the best place of any to ask this. I was playing around with WP 3.5E earlier today, and though I'd try saving something in RTF to check compatibility with other computers. I got the below error message when trying to do so. Saving as a WP Mac file caused no problems. I got the same error on both my Clamshell G3 and my Pismo G3.
