I just downloaded DS2024 and I noticed that my newly saved drawings (R2018) do not show the contents of the model space window in the saved preview. In DS2023 it worked, now all it will show in the preview is the layout view. 

Also, when I copy objects or mirror it changes all the properties of the copied items to the current layer, so if I copy an object on layer 0 and object on the text layer and dimension layer they all are on the 0 layer.

What changes can I make??
