VFP5 compatible version :)

*BeforeRowColChange
  if mdown()
    lnBottom	= objtoclient(this,1)+.headerheight+.relativerow * .rowheight
    lnTop	  = lnBottom - this.rowheight
    lnMouseRowPos = mrow(wontop(),3)
    lnMouseColPos = mcol(wontop(),3)
    llChangingRow = !(between(lnMouseRowPos,lnTop, lnBottom) ;
                    and between(lnMouseColPos,;
                    objtoclient(this,2),objtoclient(this,2)+.width))
  else
    llChangingRow = inlist(lastkey(),24,5,18,3,145,148)
  endif
