Thank you. I will look into changing this. It looks like he same also the case
for WM_SIZING? Looking at http://bugs.winehq.org/show_bug.cgi?id=5941 this
seems to have been the case for a long time. WIll it ever get fixed?

There seems to be a problem with AdjustWindowRect(). When I try and process
WM_WINDOWPOSCHANGED on Wine the values returned look to be off-by-one and to
make it work at all I had to change the code to be as below.

    ar->top    = 0;
    ar->left   = 0;
    ar->bottom = 0;
    ar->right  = 0;

    if( AdjustWindowRect( ar, svb->style, FALSE ) )
    {
      if( mode & MODE_WINE )
      {
        dr->top    -= ar->top    + 1;               // Client Area positions
        dr->left   -= ar->left   + 1;               //
        dr->bottom -= ar->bottom + 1;               //
        dr->right  -= ar->right  + 1;               //
      }
      else
      {
        dr->top    -= ar->top;                      // Client Area positions
        dr->left   -= ar->left;                     //
        dr->bottom -= ar->bottom;                   //
        dr->right  -= ar->right;                    //
      }
