Symptom
When you try to change a filename extension in the Name & Extension field of the Inspector version of the Info window, you experience these symptoms:
- The Finder becomes temporarily unresponsive, and the spinning disc pointer appears.
- A blank alert box appears, sometimes with an OK button.
- The Finder window and Inspector window disappear.
- The Finder restarts.
The computer is unresponsive for only a short period of time, perhaps 30 to 90 seconds, depending on your configuration. The computer functions normally afterwards.
Solution
If you need to change a filename extension, use the original style Info window. This is the default Get Info behavior in Mac OS X 10.2 or later. The symptom should not occur if you are only changing the first portion of the file name, leaving the extension as is.
Additional information
Mac OS X 10.2 offers both the original (Figure 1) and later (Figure 2) styles of what is now, in either case, called the "Info" window. The later style is also known as the Inspector. The appearance of the window types differs slightly.

Figure 2 Inspector style "Info" window
