  | Look for "Fun with fields" and download that.

  | scrollbars :-)

Hi Klauss,

Nice your Banana :-)
in fact, the stack "Fun with fields" doesn't manage the enable/disable
property of the thumb "banana"
( i set the text shorter than the height of the field,
but still can move your banana all the path from top to bottom )

i did add these 2 lines into my card script :

  put the number of lines in field f * textheight of field f into n
  set the enabled of btn "MyThumb" to (  n  > the height of field f  )

Is this way valid in any cases ? any comments ?

get the scroll of field f, doesn't help in this context.

  | Before that, i may encourage you to download my cute little palette
  | from:
  | www.revolutionboard.de/klaus/heim2WIN.zip
  | Please read the dox, to install it correctly.
  | Don't panic, it's totally easy, honestly :-)

Sorry, i'm still with metacard 2.3 on windows ( only ) and it doesn't seem
to be compatible... probably i should need to move to 2.4 one of these days
?

Viele Dank, Klauss
