Linetypes do not work as expected

Hello,

Linetypes do not work as expected. I have noticed that this problem occurs with lines that refer to ltypeshp.shx (in the file mm.lin).


For exemple, for the fenceline circle (----0-----0----0-----0----0-----0--) I have a discontinuous line (like: _._._._.) on draftsight. How can I fix that?
