Hello

I have connected gnus to my gmail account via nnimap. (No agent involved)

My INBOX was large (5042 messages) and I reduced it drastically using
thunderbird (since this is faster).

Now the INBOX contains 115 messages.

However when I try to enter the INBOX (group) gnus keeps telling me that
it contains 5042 and offers me to show 200, when I do this, I only see
19 messages (read). When I demand to see 5042 he shows me the 115
messages which are actually in that INBOX.

It seems that some index needs to be actualised but how? 
I tried gnus-expunge-group, without success.

Any help is appreciated.
