In Entity Diagram Relationship's lines behave weird

[Csányi Pál]

Hi,

I am trying to use Umbrello to design an SQlite database. It should be
OK to me to get SQL code only from the diagramm.

But, during design of the Entity Relationship Model the lines of
Relationships behave weird.

The attached image can best explain what is happening here.

What can cause this weird behavior?
How can I solve this problem?

Best, Pali
