Hello - so far I do not see this in the latest here. Can you try updating to 6.18 and see if it is any better?
@ranjit - the developer says:
It sounds like you may be getting formatted text in the clipboard when you copy the text. That happens with many (most) windows programs when you highlight text and Ctrl-C.
Then when you paste Ctrl-V into a Rhino text edit box, the formatting is maintained. If it’s different than what the Annotation style specifies, the differences become overrides.
Does that sound like what you see?
Specifically, what text box are you copying from and what text box are you copying to?
About the second part of not being able to remove overrides, what you have selected both in the Rhino model and in the edit box are significant. In order to help with that, I need very specific info about what and how you pick, where you click etc to see what’s going on.
If you click a text object in the model and either don’t click in the edit box or select everything in the edit box, the remove overrides should work. If it doesn’t something needs fixed.
