error message appearing long after crash?

[ixfd64]

A while ago, a program at of our office computers inexplicably stopped running. However, the "<program> has encountered an error" message did not appear until three days later.

Is this normal? Has this happened to anyone else before?

The Event Viewer shows two "Application Errors" associated with the program. However, only the first event had the red X icon. Also, I saw only that one error message, and I only needed to restart the program once. Or does Windows Server 2003 have a feature that tries to restart crashed applications?
