Hi, this is a minor problem in the GUI program: - have the window with installed function packages open - right-click on any package, then select deactivate/delete... - a new small dialog appears asking for confirmation - hit the Esc key with the intention to cancel the operation (effectively to choose "No" in the dialog) - but this is treated like a "Yes", and the package is deleted (or an error about missing access rights occurs) This is only about using "esc" on the keyboard, not any problem with mouse clicking. Not sure whether this is a GTK issue or fixable by gretl itself. thanks sven
