Bit of a funny one for me. Dont know if it is AutoCad on my machine but I have never seen this before.If I am working on a layout tab, with a titelblock and a viewport, When I save the drawing with the Layout tab selected, it saves the file, but reverts back to showing what is drawin in the model tab!!!!! Help  Thank you.

Are you perhaps saving to an older DWG file format?

Think youre right. Using LT2012 and saving as 2010. Thank you for the quick reply.
