This answer does not work as the execute dialogue box no longer works with the most recent update of java 5 and you can no longer download the older versions.

Hi Hans,
My operating system is windows vista and i am running on java 6.1.
When i click the save button nothing happens, there is no error message or even an attempt to save.
I downloaded version 3.0.
I will try installing SH3D again as i am also unable to export to OBJ.

Mathew.

I have downloaded loaded sweet home 3d but i have now found out that i am unable to save my work. Is there a way of copying this work in to the online version of the program in order to save what i have already done.
