Phantom Gmail Messages Cannot Be Deleted

[Chris Gordon-Smith]

Hello All

I'm new to gnus. It looks good, although its quite a learning curve.

I have a problem with some 'phantom' messages in my INBOX which just 
won't go away.

I often display all messages in a group with /o, and that's when these 
messages become visible. On new messages that have arrived over the last 
day or two, B-DEL works fine. But with the phantom messages I just get 
'Cannot delete article {7688)'. Where 7688 is the article number.

Any ideas welcome.
