Windows 7: HOW? Make show desktop TB NA button permanent

I use Dale Nurden's great TCLOCKEX (Taskbar clock extension) from XP fine under Win 7 with the classic (non Aero) skin. It allows one to change the time/date display's font size, family, color, etc., and has a customizable pop-up calendar. Here's picture of how the notification area looks when it's working correclty on the left:

But it has a display bug that's annoying: When I start Win 7, the taskbar notification area's Show Desktop button at right isn't there (as shown to the right), but appears when one clicks the up-chevrons and aborts what it invokes. However, with the button absent, TCLOCKEX ends up smashed into and past the right edge of the tray (chopped off, as shown to the right).

Anybody know of a Registry setting that can be tweaked so that the Show Desktop button is always there, from start-up of a profile? That'll head off the TCLOCKEX display bug. <GROAN...> Why does it go away?

IMO this is something that only the programmer could fix
