I just checked, and the TXT file was displayed using a sans-serif font. I'll take your word that they would be previously displayed with the serif font, since I've never before loaded a TXT file onto my Reader.
I don't know why this would happen, but still... my solution to your problem stays the same. If you replace the other two fonts with your new font, it's not like the Reader is going to whip out a brand new font out of thin air
. It will use your new font for anything you throw at it (except the stuff with embedded fonts).
