Yesterday, Mari-Lou A told me one of my posts wasn't formatting correctly (I forget which one). But I couldn't see anything wrong, and while we were exchanging comments (to the effect that both of us were using the Chrome browser under Vista), apparently her problem went away.
A few minutes ago I noticed that this post of mine was completely misformatted. Using "edit" to check the actual text I got the impression things were going wrong wherever I'd used asterisks to delineate italicised text.
As I write this text, I see that the word "asterisks" above isn't displaying correctly (presumably because of the asterisks enclosing it). But "this post of mine" displayed correctly for me when I opened that page to get the address for a link here.
If it hadn't been for Mari-Lou, I'd just assume my system is internally messed up. But as I write this I'm using Chrome under XP. So I don't think this is a browser or OS problem, and I doubt it's peculiar to just us two.
This looks like a bug. Does anyone know what's going on?
This might be a valid screenshot of this screen (I don't see the second "this" there)...
EDIT: I don't recall rebooting the XP machine this post was written on yesterday. It's my "home network server", which I usually turn on/off when I get up/retire. I did that today and everything displays correctly.
Since two users have just experienced what looks like the same problem under two different OS's, I think this post should remain open in case it affects others in future. But I don't know if "problem resolved itself without explanation" is a valid reason for removing the bug tag, so I'll leave that for others to decide.
