Just bought WindowFX6, installed it, and have been trying to use it. For the most part it works fine, except for the following:

 - Enable "Make inactive windows semi transparent"

 --- My inactive windows successfully become semi transparent (a bit too transparent)

 - Drag slider to increase/decrease transparency

 --- Result: Nothing. Expected result: Sliding the slider would change how transparent the other windows are.

There are similar sliders for other features and they successfully work, just not this one. Looks like it is not connected up correctly.
