You are correct, my installation was strange, thanks for pointing it out.
I have now reinstalled from scratch, without the MSYS special compiler.

I understand now that MinGW's role in MoveWindow() is only to link to the
system's DLL.
Still, MoveWindow() freezes on me, and I don't know where things go wrong.
I don't know where to look either.
How can I check if libuser32.a is doing its job as intended, if my user32.dll
is working fine, and anything in between?

Could someone perhaps provide a basic sample source code using
MoveWindow(),so I can check that my problem is not with OpenCV?
