Ordinate Dimension Problem

Hello to all,

I am new to Draft Sight and am experiencing a problem. I hope it can be resolved here. The problem i am having is with the Getting Started PDF on page 136 concerning using ordinate dimensions. I am using the new version of Draftsight V1R 3.2. I believe that I followed the instructions properly, but when I try to select points for continued dimensions it rubberbands dimension extension lines all over the place. Can anyone tell me what is wrong, or what I am not doing correctly. I am currently using Windows Vista Home Premium.  Thanks in advance
