the mouse position drift in high DPI with the radwindow move!

[wu]

I feedback the question,but it is not still resolve,so when i got the old source code,

after i deal with the gridview column resize,i found the question code:

in ChromelessWindowHelper.cs file:

modify the function HandleMoving(IntPtr hwnd, IntPtr wParam, IntPtr lParam, out bool handled):

just none the following code:

//NativeMethods.CopyToRECT(position, ref currentPosition);

so it is OK! i think when coordinate transform from int type to double type and then from double type to int type,

at last,there is the offset.
