Do you delete and recreate your source tree each day, or do you rcs
update? The reason i ask is that i spent most of the day fighting with a
crash that wasn''t the same as yours, but looked like it might have been
related. I finally decided to unpatched the most recent BK changes, and
at one point it took off working again, and has continued even though
i''ve now repatched.
