Thanks Nadya,
Yur message got me started, but I found that this works for every resize() I could think of.

with Column
  lnWidthTotal ;
    = 3 ;
    + IIF(.DELETEMARK,8,0) ;
    + IIF(.RECORDMARK,10,0) ;
    + IIF(.SCROLLBARS>1,sysmetric(5),0) ;
    + .COLUMNCOUNT
  for each loColumn in .Columns
    lnWidthTotal = lnWidthTotal + loColumn.Width
  endfor
endwith

Do you have any idea why my formula works better for me? Maybe different screen resolutions?
