If I first paste from the large file into a new file and then on to eM, I don’t get it either.
So for now, I’ll consider it a quirk in the WordPad formatting.
It may be because the large file was started in XP or something.
Win 7 added more colors for WordPad, so maybe it’s adding some extra control character to older colors that’s now tripping up eM.
I copied all the content in a new WordPad file and it seems ok now. So that would be my best solution.
However, all other rtf’s coming from XP still do it, so I’m pretty sure it’s a quirk that arises from opening older files in a newer OS (and possibly to do with the extra color assignments in WordPad after XP).
So, if you want to emulate it, make a file on XP WordPad first. But I will be fine, thx.
