You can specify whether the prompt to resume on presentation restart should be enabled on a template-by-template basis.
To enable or disable the resume option in Articulate Presenter '09, do the following:
Go to Articulate > Player Templates > Player Controls.
Check or uncheck the box to Prompt to resume on presentation restart.
Optionally, you can also check the box When running in LMS, ignore Flash cookie. If selected, your presentation will rely on the LMS to resume properly. If you're unsure, leave this box checked.
Click Close to save your changes. If prompted, assign a name to your player template.
