    It happens every time I'm trying to change global settings. Furthermore, it won't allow me to press "OK". I have to quit and start over.

    It is trying to get an access to files like ".hg/.hgrc-jyboda". The content of those files (and I have them a lot) is "# Generated by TortoiseHg settings dialog". After I choose "retry" the dialog closes and configuration saved. Also, there is nobody accessing those files - they created when I push "OK" button in the settings dialog.

    Thanks. I guess some application (or TortoiseHg itself?) watches new file and locks it temporarily.

    If you click "OK" button, TortoiseHg

    1. saves settings to temporary file, e.g. ".hg/.hgrc-jyboda"
    2. then, renames it to ".hg/hgrc"

    If another process watches .hg folder and detects 1, it may lock temporary file. Since TortoiseHg tries to rename it immediately, "[Error 32]" occurs.

    Not sure. You've already tried to disable virus scanner. I have no other idea.

    Temporary workaround may be inserting slight delay before rename():

    # ...
    import time
    def _rename(orig, src, dst):
        time.sleep(0.5)  # [sec]
        return orig(src, dst)
    # ...
