I'm unable to reproduce. Do you delete clicking on Delete button/icon or
pressing Delete key?

Both

 What do you have in Preferences > Server settings >
Main options?

Did you try with disabled all plugins?

yes

Did you try with different browsers?

firefox 20 and chrome

Did you try with different skins? What skin? What

We use classic because larry has always had issues here (never shows other mail folders, chops off bits here and there - but I put it down to our desktop OS's - ubuntu and suse) which means it likely might occur for users as well, so we default to classic.

browser? Did you try to check what request (if any) is sent to the
server? 
If request is sent could you provide it's content and imap_debug
log from this moment?

Ok, from this we have established that it is due to these conditions
page limit 50
deleted messages more than 50, I use LKML for my test, giving me 700 messages plus.
click the all messages icon, selects all 700 (when I checked before it had 12K messages to delete)

unselect any single message or more on that first page <--- when this occurs it changes the behaviour to " only delete on this page"

I didnt notice this in my previous test given the first pages were all from the same poster, when imap_debug showed deletions I then took more notice of the tl message count and as tested again the count infact reduced, re-tested a few times more and concluded this is what it is doing, rather than deleting all messages less the unselected ones, once you unselect a message, it will then only delete the remaining highlighted messages on that single page.
