You don’t need to show all the layers before you save your file. All the content is going to be safe no matter if it’s visible or hidden. Layers are just a way of organizing your file.
Ok, great, thank you for your quick replies, I really appreciate it!
(I am also using Matrix ver8, and there is something called job bags…I guess it isn’t really a “save”…I shall find out more about this! I have not been saving every time I job bag…perhaps I should start to do that as best practices!.)
