I have noticed a number of Windows 98, Second Edition machines exibiting the symptom when an application is closed, the tasbar button associated with it (is now blank - a ghost button) remains until clicking on it. Has anyone else encountered this same situation? I have not been able to identify a common denominator yet, i.e. what program closing exibits this symptom. Also, I am not certain that this is limited to Windows 98, 2e. Internet Explorer 5 is installed on each and auto hide is enabled on the taskbar, which may be a contributing factor - especially as to determining the common denominator.
