Dimension command

Hi everybody. I am new using DraftSight, I am more used to drawing in AutoCAD 2008 (Yes, old version). I really like DS so far, except for the Dynamic Input, you know the free version does not have it. Hope someday it will, I really miss it. But now I have another problem. Until yesterday I was using DS in my laptop with no problem at all, but today I started using it in a new desktop computer. my problem comes with de DIM command. See, till yesterday in my laptop, I used to type like in AC, DIM and then HOR, for instance. Now I can't. The DIM command does not exist! I have to write HORIZONTALDIMENSION, VERTICALDIMENSION, etc... Does anyone know how I can have that old-fashined command version? Thank you all very much.
