Thikening the contour of an square crashes Impress

There are a couple possibilities which come to my mind as to the
problem here;

          assuming there is no bug in any of your set-ups - which could be
1 cause.

       Another possibility is that you're attempting to stretch an existing
line rather than deleting the present one which you no longer desire;
          if this is the case, then merely delete that which you no longer
want & replace with that which you want.

       Another possibility may be whatever you mean by 'arquive' ???;
          do you perchance mean archive?, as in saving the document?
          if this is the case, then are you saving with a different name?,
or are you starting fresh with a blank PP?
       You might try starting with a fresh/blank PP
          then click on add file
             then make any adjustments to the individual slides you want
                then save the document with a different name;
       Should be as you desire it,

       Hoping this helps,

Anne-ology,

thanks for your reply.

Well, I really don't know if this is an bug, but i can repeat it consistently
in impress.

No I'm not streching an existing line, I use the square tool draw the square,
clean the fill in and them I try to thikening the line and it crashes.

I mean with arquive, when I open an new clean/blank/fresh impress file, where
the only object I have draw is the square draw which I create the same way I
described above.
