How does DO9 save the history for search/find and rename/replace? I don't want the history to be saved with the configuration.
Edit: I found it in the .osd-files (folder state data). But there're a lot of other informations. It looks like windows position and more is also saved here, so I can't just delete the files.
Question: Is there a way to disable history or maybe I just could write protect the files?
I'm sorry I missed the intent of your original question. You were talking about history within a field or a dialog, not your Undo history.
I do not believe there is a way to clear those at the moment, aside from deleting the XML files that store them. I haven't dug into this yet, so I don't know which files clear what.
I'm think I'm going to put ClearMRU on my list of User Commands to create (with switches for each MRU file). There I are some things I always want to delete, and others I'd like to keep.
