I just noticed that Windows has the file dates backwards. I have Explorer set to show the Date Modified. Yesterday, I noticed that the dates weren't changing on files that I had just edited. Checking the Properties dialog, I discovered that the Created: field appears to contain the Modified date and the Modified field appears to contain the Created date. Here's a screen shot:

The Accessed field appears to be correct.
Can anyone suggest what might be happening and, what, if anything, I can do about it other than upgrade Windows?
