Has anyone else had one item overwrite another?

[quant]

ok, I'm breaking my principles ... partly because Kinook didn't resolve it yet ... I hope it makes you happy

create any item say item1 and open it in two tabs
go to second tab, and "shift delete" this item1
close second tab

Now note that the first tab still shows item1 as active altogether with its content, but in the Data explorer tree the focus is on another item, and typing now anything inside, you are actually rewriting the content of this focused item

and I have a feeling there might be various similar tabs related problems still unresolved ... but this might show what might get wrong so hopefully help in finding the others as well
