Here is my recipe (also seen in the attached video):
1) Two text frames filled with text and some paragraph Text Styles including one for initial words.
2) Text frame on the left has already one paragraph formatted with initial word(s).
3) I pick a paragraph in the right text frame and apply the intial words Text Style.
4) Now I switch to the Move Tool and click the left text frame.
Result: The one paragraph formatted with initial words is reset.
Any reasons for this annoying behaviour or workarounds? In fact "First Word Off" appears in History. My workaround for now is hitting the ESC key twice.
PS: Video shows a beta, but in the retail version it is the same. I have done this to prevent any interference with already used Text Styles in my retail version.
