Select entites in a 2D dwg

Not sure what I'm missing here but I have trouble to select entities in the 2D drawing?

Any setup needs to be done? SW seems to ignore when I tried to use the cursor to select the lines or points of the round shape such as shaft

I never had trouble like these with SW2007 - I bet 2009 should be better and am sure something missing here

Thx, Chris
