Why does unmanaged OnPaint functions give OnResize errors

P: n/a
I have a PictureBox where the overriden OnPaint method looks like this:
---
IntPtr hdc = e.Graphics.GetHdc();
DLLWrapper.DLLWrapperDrawFrame(hdc, 0, 0, this.Width, this.Height);
e.Graphics.ReleaseHdc(hdc);
---
The DLLWrapper function causes hdc not to be released and error "Object
is used elsewhere" appears.
The strang fact is that it only occurs when I resize the window. Even
the VS .NET 2003 environment tells in the PictureBox that the object is
being used elsewhere.
Does anyone know a workaround?
