I for myself did not, but as there are runnig automatic jobs periodically I can't tell, if one ran in the time while I was testing (but I guess not). At starting my tests all rows contained a zero for all tokens and there should be no ones at all. In my case rows with token set to one are really rare, about one of a thousand rows. I looked for fast way to find therse rows. I'll try again after a successful run - not resetting the token (not using analyse this time). Cheers, Jan
