One explanation for the change of font is that the text is formatted using styles, and the same style name may have a different definition in the destination document.
Steve you are THE BEST!. I called Adobe two days ago, they couldn't fix it, I talked to 4 different people and I'm still waiting for their call back today.
Your answer fixed my problem. thank you so much!
I do have another issue though...when pasting text between InDesign docs that don't have a text style, the font and color will change.
I tried to fix the font part by changing the basic paragraph (default) without any InDesign doc opened and checked the "no break" option under paragraph styles options/basic character formats/not break. I fixed one but the text color still changing.
Any idea how to fix it?
