_ScreenCapture_CaptureWnd() Needs WinActivate() First?

[BruceCopperField]

Is it a must for the window to be WinActivated() before I can use _ScreenCapture_CaptureWnd() on it?

All that capturing the window does is find the window region and capture it using _ScreenCapture_Capture. As a result, it will take whatevers in the window area, so a non-active window may be covered by other windows. It is not a must though, but you probably should.
