unittests and Windows App

[ref2401]

I'm using D 2064.2 and VisualD 0.3.37
VisualD "Redirect stdout to output window" checkbox is checked.

In simple ConsoleApp unittests work properly. I can debug them 
and assertion fail results are printed to the Output window.

But it seems that unittests don't work at all with any 
WindowsApp. It's impossible to debug and no assertion fail 
messages are printed to the Output windows.
