MZ-Tools 8.0 for VB6 takes less than one second to load on modern hardware. If it takes several seconds, likely it is because it is running on Windows 7 or higher with compatibility mode for Windows XP. While this configuration solves the slow dragging of controls on form designers, it causes a delay loading any add-in that creates many buttons on the commandbars. If this delay is unacceptable for you, turn off compatibility mode for Windows XP as explained in the help file.
