Strange behavior with a window

Hello,

I'm having a problem with the viewing window on my program. The window opens normally and displays the desired model (IGES), but when I move the mouse cursor over it, the mouse icon changes to that of the "busy" icon. If I click on the window, the program stops responding.
It's a Win 32 console app, running on a 64-bit Win 8.1 using Visual Studio Exp 2013 for Win Desktop.
I tried using VS's local windows debugger, but when I do so the program doesn't crash when I click on the window. The window remains unresponsive, and because there was no crash, nothing appears on the debugger for me to investigate.
Here is a simplified version of the relevant portion of the code. Any clues? I plan to include mouse events for model manipulation, so i can't have this problem happening.

Thanks in advance.

Solved. Well, not SOLVED, but I got around it. I had to change the line:

Handle(WNT_Window) aWindow = new WNT_Window("Teste Inicial", myWClass, 1, 1, 1, 600, 600, Quantity_NOC_MATRAGRAY, 0, 0, 0);

and use instead:

Handle(WNT_Window) aWindow = new WNT_Window(Hnwd);

Where Hnwd was created based on the code I found on the following link:

So basically I had to abandon the OCCT window creation method for the less easy Win32 API one.

Thanks!
