Application to List Programs in Memory?

There are several.

Go to your favorite download site, and search through the utilities and windows add-ons sections.
I like www.nonags.com
www.completelyfreesoftware.com
Since all of their software is free-ware.

I also believe that Sandra from sisoft.com can display the active processes.

I know that there are also options within Ontrack System Suite, and Norton Systemworks to view active programs and processes.

You can use Kernel Toys. You can download here:

Look for "System Tools" in "Accessories" and put "System Monitor" on your Desktop.
Add "kernel processor useage", "memory in use", and any other sections you desire.
