Prologue: I've been searching for a solution for this problem and couldn't find any. Perhaps I don't know how to search properly. The problem itself isn't catastrophic yet it is really annoying to me, as I like to work quickly and everything has to be on its place (OCD?).
Problem: Once I opened again my InDesign (CS6 v 8.0.2) and when using Text tool, I noticed its options has changed places and I don't manage to change it back. It is hard to describe the problem in words but I uploaded the image. Hopefully this helps to solve it:
Thank you for your time!
On the left side of the panel you'll see the "A" and the carriage return symbol.
Picking one of these switches the panels.
It solved my problem! I kept trying to drag panels into their places, also checking preferences, workplace options and everything else.
I can now finally work in peace, without being confused all the time, thank you very much, Eugene.
