Need to turn off radial arc extension line for radial (fillet) dimensions

We are evaluating DraftSight V1.4 in my department and are comparing it to Autocad LT 2006.  One of the things we noticed different was when dimensioning fillets with the radial dimension annotation.  In DraftSight, a radial arc extension line appears when placing the dimension on the opposite side of the centerpoint.  In Autocad there is an option to have this phantom arc shown or not shown.  If set to yes (shown), it behaves like DraftSight is currently behaving showing the radial arc extension.  If set to no (not shown), Autocad continues the arrow head to the radius.  I cannot find an equivalent setting in DraftSight to do the same thing to not show the radial arc extension.  Is there a setting in Draftsight I can change to behave the way we want, is this going to be addressed in a service pack, or is this the intended fuctionality and not expected to change?

Any info or help would be appreciated.  Thank you.
