Hi Stewart,
Do you wish to import all tasks from a project file to another or just
selected tasks? If you wish to import all tasks, you can insert the
"old" project into the new project through Insert > Project. In the
Insert > Project dialog box, you can select or de-select the choice
"Link to project" to either maintain the original "old" project file
(linked) or just insert the tasks to become part of the new project (not
linked).
I hope this helps. Let us know how you get along.
