Further testing ... It's a tedious process to track bug as there might be multiple factors that might be contibuting.
I have multiple screens. Opening the example room i downloaded (http://www.sweethome3d.com/examples/userGuideExample.sh3d) works fine but some drawings i've been doing don't
. Usually the main problem is i can't dock the 3d view anymore.Anyway i'll open a new thread as i've been hijacking this one enough now.
