After editing the index file, I try to save it. The name of one of my image files blinks rapidly and the program freezes. The save cannot be completed and I get the error message: "Access violation at address 006E727E in module 'coffee.exe'. Read of address 00000220. Happened repeatedly. Unable to save the file.

This can happen even if you are running as an Administrator, and it is caused by Windows very strict security settings.

To fix this configure the shortcut to always run as administrator. Here's how:

1. Right-click the shortcut icon, and click Properties.
2. Click the Compatibility tab.
3. Here, put a check mark by Run This Program as an Administrator.
4. Next, put a check mark next to Run This Program in Compatibility Mode For: and ensure Windows XP Pro Service Pack 3 is selected.
5. Click OK.

In the end your settings should match this:

If you continue having problems you may also need to set the application as an exception to Windows Data Execution Prevention (DEP) feature. Normally if this is the culprit, you'll get a little bubble along the taskbar notifying you, which will allow you to set the offender as an exception.

One last option that could be the cause of this, and related to the DEP feature, is User Account Controls. This is the large window that appears in Vista asking you to "Allow" or "Deny" access to functions within programs. You can turn this off within your Control Panel > User Accounts window, along the left-hand pane.

All three options let you control your system exactly how you want and give you full access to do/run anything on the computer.
