4t Tray Minimizer does not work with one of my programs but it works fine with others

It may happen if your program works with administrative rights and 4t Tray Minimizer can't access its window.

The solution is simple:

Exit 4t Tray Minimizer (Open its main window and select Exit in the File menu)
Launch 4t Tray Minimizer with administrative rights (right click on 4t Tray Minimizer icon and select Run as administrator)

Is the problem still exists, please send us the technical report as described here...
