Outlook moved drafts folder!?

My work pc has moved my Outlook drafts folder as a sub-folder of my inbox.

This is highly irritating and undesirable, and different to what it was previously - separate folder outside of the inbox, as I can see on other colleagues PCs, so it has definitely moved.

I think it is something to do with viewing work emails on web, and/or accessing outlook via my desktop using Citrix software from off-site.
Reason for this is that when I compose emails on web, I find a copy of them in my drafts Outlook folder upon returning to work PC!

Anyone got ideas on why this happened, and how to resolve?
I am using up-to-date XP and Outlook 2003.
