I can only selected it with the keyboard. you can avoid this by calling root.option_add('*Menu.clickToFocus', '1') immediately after creating the main Tk window. This doesn't seem to be documented, you can find the option in menu.tcl though. It is in the following code block in the Tk function ::tk::MenuMotion : set mode [option get $menu clickToFocus ClickToFocus] if {[string is false $mode]} { set delay [expr {[$menu cget -type] eq "menubar" ? 0 : 50}] if {[$menu type $index] eq "cascade"} { set Priv(menuActivatedTimer) \ [after $delay [list $menu postcascade active]] } else { set Priv(menuDeactivatedTimer) \ [after $delay [list $menu postcascade none]] } So you see, if clickToFocus evaluates True, the call to postcascade does not occur.
