Hi!

I just tested with MIL-Lite 9.0, one proprietary library for computer
vision, and I have a problem.

I grab sequence of image through of the frame grabber and I store on a
buffer. I tried to show the images through of the function above:

/* Display the buffers. */
MdispSelectWindow(MilDisplay, MilImage, frame->winId());

When I compile the application with qt-4.3.4 I don't have any problem,
and application work, but when I compile the app lication with qt-4.4.1
the function MdispSelectWindow() return error and indicate that return
"frame->winId()" isn't validate.

I tried to find some difference when I execute "xwininfo -int -tree"
above application compiled with qt-4.3.4 and qt-4.4.1, but I did't see
difference.

What is it happened?
