Is it possible to download older versions of DraftSight?

I just upgraded my DraftSight on my osx to R1.4 on OSX Lion.

 

I am quiet disappointed with it especially with:

  1. Loss of toolbars: I can't for the life of me enable the layer control combo box and furthermore, it seems that I can't enable any toolbars.  This crucial to me as I used the combo box to change layers on the fly of objects I select.
  2. Loss of single window display: Although I know this question has been asked before, but it is critical to my workflow

Therefore, my productivity has suffered enough and I'd like to go back to 1.2 (the version I previously had) or 1.3

Thanks
