I occasionally double click to drag an open window to a new location. When I double click in the top bar of the firefox browser, any open windows are put away, not closed...which destroys the link, but put away like clicking on the minus sign in the upper right blue bar that is next to the "fill page" icon and the red X that destroys the link. This may be a property of MS8.1 POS or it might be Firefox. I am sick and tired of having to open all these windows one by one each time my finger "stutters" producing a rapid double click. I have tried changing single click and double click response delays, but that does not help either. The morons that wrote MS8.1 load the keystrokes instantly without checking timing. Also, does anyone know of an operating system that emulates the MS NT system without all the F------ "features" that pervade later OSes??? Many Thanks for your suggestions!!!
