Save As keeps prompting for saving READ ONLY (not

My top-down model is going on well. I got a lot of support from this forum - Thanks.

My current issue:

When I save the assembly (Ctrl+S), I keep getting to save a bunch of read only documents. Only option is to hit "Cancel" button because they are read only (not edited in the current session and not checked out as well).

Could someone reply me to do without this prompt.

Thanks.

For example, I had to hit "Cancel" for the followings:
