rectangle input

in the old version i could put in the horz and vert  dim as such  6,9  it would draw a rectangle 6" x 9" , the new version, will not let me place the horz and vert numbers on the command line.   it asks for start point, no problem.  the the next point.  i can drag the cursor and get the rectangle, but i cannot input the two numbers. how do draw the rectangle in this current new version ?
