Yes, that has been an ongoing experience for myself for quite some time now. This is not just a problem here on this forum but it crops up on the ARC forums too where I have actually read the message and then have received notification via eMail that there is a message waiting for me to be read. A bit perplexing but figured it had something to do with sun spots, phase of the moon, NSA, FBI, etc. or more to the point, events or agents over which I have no control.
