problem with grouped field

[MisterX]

looks like a bug. I can reproduce it too (w2k).

try this instead.

use a vertical scroll bar:
 - start to endvalue = 0-32000 
 - page increments 1..

put the scrollbar right of the field as if it was the fields' 
scrollbar... Should fool anyone ;)

im still experimenting with a smooth movement (number wise...)

on scrollbardrag w
  put w
  put the height of fld 1 div the textheight of fld 1 into mylines
  put (the endvalue of me / the height of me) / (the endvalue of me /
mylines) into movementfactor
  put round(w * movementfactor) into myvalue
  repeat with x = 1 to mylines
    put myvalue + x into line x of fld 1
  end repeat
end scrollbardrag

it's not fast but it works linearly for number movement...
Alas it's not correct to get to the big numbers...

The mylines (the number of lines in the field) should increase like:

on scrollbardrag w
  put w
  put the height of fld 1 div the textheight of fld 1 into mylines
  put (the endvalue of me / the height of me) into movementfactor
  put round(w * movementfactor) into myvalue
  repeat with x = 1 to mylines
    put myvalue + x into line x of fld 1
  end repeat
end scrollbardrag

which almost gets to 32000... I'll let you find the quirks ;)

hope it's what you want... If you want the stack I made it in
let me know off list ;)

cheers
