I keep having trouble with change bars staying in the document - it's very random. FM17 and I am all patched up. I shouldn't have to go page by page to make sure the change bars are removed.
How are you removing them?
To remove all change bars (automatic or manual):
Format > Document > Change Bars > Clear all Change Bars
Yes, that's how I cleared them, but there are always some that just won't clear, not sure what the issue is with FM17.
And how are you adding them? Automatic with edits, or via a paragraph or character tag? If you are adding them via a tag, and then Clear All Change Bars, you'd be overriding the tag definition. If you later update the tag, and remove overrides, they would return. Could that be what is happening?
If not, and you think it's a bug, you can report it here: Tracker.
