STR #1057: A window that is needed to correctly manage a timer on WIN32 (personally, I would like to mark this WTF ;-), was actually visible. I resized it to 0x0 ixels, but if that fails, we fall back to the old 1x1 pixels. I also removed the "default" positioning since that messes up the default window stacking for pedantic users.
