When I add a term to a term base using either the menu functions Add New Term or Quick Add New Term, the Termbase viewer comes up and does zillions of rewrites, first for all terms listed in the view (starting from the first term in the Termbase (sic)) and then repeating the whole rewrite process for each term around the term added - in some cases the rewrite process is even repeated for a third time!! During all these rewrite phases - can last about 5-6 seconds on my fast PC, nothing else can be done but wait. Improving this behaviour by cancelling the rewrits could make a huge performance boost!
