cannot pick bend lines in a drawing

Hi,

Has the work flow for dimensioning to a bend line changed in Ver 2013.

Before I could select an edge then select an end point, or the bend line itself to dimension.

For some reason in 2013 I can select the edge but it does not highlight either an end point or the bend line for my second selection.

All I can do is select somewhere near the line to create a dimension.

Is there a setting that needs to be checked somewhere?

Attached is a drawing with a flat patten to get the dimension I select edge of plate then select somewhere near the bend line ( it comes out at correct dimension 315.5mm).

Could someone see if it works as before on there computer?

Please note that I have taken proprietary info off drg and also drawing is not yet complete.

Thanks
