Hi there, When selecting “Restore Defaults” in the Options dialogue via the Edit -> Options menu the following application error is received: window name "!paving" already exists in parent while executing "ttk::frame $w.!paving" (procedure "pave_toplevel" line 4) invoked from within "pave_toplevel ." (procedure "apply_config" line 37) invoked from within "apply_config" (procedure "do_restore_defaults" line 14) invoked from within "do_restore_defaults" invoked from within ".options_editor.buttons.restore invoke " invoked from within ".options_editor.buttons.restore instate !disabled { .options_editor.buttons.restore invoke } " invoked from within ".options_editor.buttons.restore instate pressed { .options_editor.buttons.restore state !pressed; .options_editor.buttons.restore instate !disabled { ..." (command bound to event) Tested using Git Gui 0.21 as included with Git 2.13.2 x64 on Windows x64. Also tested on a Windows VM with a clean install of Git. Kind regards, Samuel Leslie
