I did purchase Smartdraw 2007 for my students and myself recently and again because of very positive experience with earlier versions did not make use of the trial offer. Unfortunately I have to say that I am considering to move back to Version 7, even if I do loose some of the improvements added in version 2007 and for which I did purchase the new version. My main reasons for this are:
1. Reduced workspace. I don't know, where Harold gets his 50 pixel story from, I measure 110 pixels in Vers. 7 (or 55 without toolbar) and 240 in Vers. 2007!
2. Converting drawings and symbols created in earlier versions of Smartdraw generates a large number of errors (changes of hatching, rotation of objects, etc.) which are difficult and time consuming to fix. For me missing backward compatibility can not be excused. Complaining to Smartdraw Support about this gets you the answers that this caused by the new drawing rendering engine and if you have sensitive data, keep a Vers. 7 running on your computer.
3. Several commands can only be accessed through the Vers. 7 menu bar at the top (e.g. HELP Content, Hairlines, Border Style, etc.)

My main problem, however, is the reduced workspace, which can not be changed by work-arounds.
