You are probably right about the learning curve - I have had about 10 years or more with the previous versions and although this is completely new, it does come from the same origianl developer, so you get to kmow I suppose the way they think and hence where to go for things that may have changed a little.
You would probably find it advantageous to get through all the Program Settings options, consider each as to how you would like to work and choose accordingly - then if something does not seem to be quite right you may recall something that you have turned on or off and hence narrow the problem down.
When I first opened this version, Settings was the first place I went before anything else - then you are aware of the defaults and can set things according to the way I like to work. Second place was Building Locations. If not to your liking, change the default settings (I always work with 3 metre walls for example for most of my projects) because everything you do will work to these settings by default. Third stop is toolbars, turn them on and off and Apply, so you can see where they are and then mouse over each button to see what the tip indicates it does. At this point is a good time so close the program, save the Project1 template and that way preserve your changes. If you happen to crash it some way after setting everything up and lose them all again it is quite annoying. When you open it again it will work in the way you have set it up - now I was almost ready to start!! I say almost because the Fourth thing I did was to read the manual - that was the hard one - at 300+ pages it takes a while but I did it and you will be surprised what things I picked up dispite being familiar with earlier versions. There are lots of little short cuts and traps for the unwary, so it was worth the effort. At least look at every page and you will pick up a lot.
