First try running Do It Again in Windows XP SP3 Compatibility Mode (Google this for instructions on how to do so in Vista/7 -- [right-click Do It Again in the Start menu >> left click Properties >> Compatibility tab >> choose Windows XP SP3, and check Run as administrator]).
If that doesn't work, uninstall Do It Again, log into the computer with a user account that has administrative privileges and reinstall Do It Again.
Finally, if all that doesn't work try disabling User Account Control (Google this if you need help -- it's in the Control Panel -- User Accounts) -- Vista/7 only.
Can I automate Do It Again? Can I run it in the background? Can I schedule tasks to run? Can I edit the task files by hand?
Yes. These questions (and more) are answered in the help file (Help >> Contents >> Common Questions).
Tasks are saved as .dia files in the folder Do It Again is installed in (like C:\Program Files\Do It Again\). You must have permissions to view this folder to be able to edit the files. If you don't have the appropriate permissions and can't get them, uinstall Do It Again then reinstall it inside your Documents folder (change the install folder during the install wizard).
My keyboard doesn't have a Scroll Lock key or F12 key, or they don't work:
Virtually all keyboards, including those on laptops, have a Scroll Lock key and an F12 key. They are sometimes hidden or abbreviated (ScrLck) or colored in a darker text to indicate that you have to press a button like "Fn" or "F-Lock" in order for them to work.
The only choices for this button are F12 and Scroll Lock. To choose between them click Options >> Set the Task Done/Cancel Key.
If you are still having problems with Scroll Lock / F12 on your keyboard, especially laptops, you are likely not the only one who has had problems with that same keyboard. Search Google for your model of keyboard/laptop and Scroll Lock or F12 and you'll likely find the answer for your specific keyboard.
