Many thanks. This is a problem with using connectors for charts such as this - you have two options
1. Use normal links (Link class) instead.
2. Below each item in the org chart that has multiple children, place an invisible small shape that you connect one connector to, then connect the rest of your connectors to the hidden shape. You can set DrawBorder to false to make this easier. I havent tried a shape 1x1 pixel but you will need to set the MinimumSize property to 1,1 first.
In version 5, connectors will have waypoints which will solve this issue. V5 has been delayed to first quarter 2008 to coincide with the vs 2008 release.
