Glad you are liking the tool pavlovapete. ;)
I am about 99.5% sure that the too-quick timeout you describe is a tech issue and not a 'feature' - and I'd bet that engineering is at work on a resolution.
Yes, I am being a little bit vague - mainly because I am not actually at work today, and, therefore, have not consulted with my usual tech contacts. :)
