I checked my browser settings and that made no difference. I tried InPrivate browsing and that appeared to work but was not 100%, maybe the messages I could not access were replies to me that had been deleted by the moderator in which case I would see them in my email but they would not be in MSN comments. I tried a different laptop that did not have any changes to it and that worked fine except for replies to myself which had been deleted by the moderator for policy violation - nasty right wing rabble in this country now. That told me the problem was on the original laptop; the only 2 changes I had made were with Windows 10 update and changing my antivirus software. I bet it is the Anti-virus software.
