The added ..in yourtable.. will make sure that the updated will happen even if you are on the "phantom record" in the selceted work area. Another shot in the dark, could this user have little space left in his/her temp directory?

As I wrote, this syntax will work unless you are at the "phantom" record, record number reccount()+1, in the active work area. That's why this syntax is a no-no in real life.

>>Regarding selecting form a cursor into a new cursor with the same name, that's safe and sometimes a real timesaver. I use this for instance for wildcard searches in a table, a la google, where my users types in different words in a textbox, and want all the records where all the words are in this table. My code is something like
>>lcTarget='curDummy'
>>For x=1 to getwordcount(lcLongText)

>>      lcTable='mybigtable'

>>     lcTable=lcTarget
>>   endif
>>   lcText=upper(getwordnum(lcLongText,x))
>>   select from (lcTable) where lcText$upper(field1+'|'+field2+|+field3) into cursor (lcTarget) readwrite
>>Endfor
