This may be a legitimate message from IE5. You might take the text of the message and search the Microsoft site and see if you wind up in their knowledge base.

The messages I am describing have ONLY the OK button which closes the box. My son pointed out that for pop-up windows in general, it probably is not safe to close them with either the OK button OR the 'X' in the upper right corner. He always closes them by right-clicking on the item in the launch bar (usually at the bottom, unless you've moved it). This is probably the safest way to make sure that Windows is actually closing the window. It clearly is not safe to use the buttons within the window no matter what they say. An application can bind any procedure to any button.
