What is the values of TTTOOLINFOW_V1_SIZE and TTTOOLINFOW_V2_SIZE? I tried to search for them, but there is some very 
obfuscated C code... :'(

I am using a structure with size = 28h = 40 bytes

struct TOOLINFO
  .cbSize   dd ?
  .uFlags   dd ?
  .hwnd     dd ?
  .uId      dd ?
  .Rect     RECT
  .hInst    dd ?
  .lpszText dd ?
ends

It seems that Windows accepts it, but WINE not.
