Int 10 Fn 82  U - Video - Desqview 2.0x Only - Internal - Get Current Win  [Q]

   AH = 82h
   DX = 4456h ('DV')

Return: DS = segment in DESQview for data structure
        in DV 2.00,
         BYTE DS:[0] = window number
         WORD DS:[1] = segment of other data structure
         WORD DS:[3] = segment of window's object handle
   ES = segment of DESQview data structure for video buffer
   AL = current window number
   AH = ???
   BL = direct screen writes
       00h program does not do direct writes
       01h program does direct writes, so shadow buffer not usable
   BH = ???
   CL = current video mode
   CH = ???

Note:  this function is probably meant for internal use only, due to the magic
     value required in DX
