VFP is 9 - upgraded from 7 to 8 and then to 9 with SET ENGINEBEHAVIOR 80. MEMOWIDTH is 4.

>>I inherited the support of an application that is being resold. One of the tables is userdata.dbf. The structure is: type (c,10) id (c,3) name (memo) data (c,50) ckval (n5.0) updated (date). The indexes are ID and USRINFO. USERINFO is a bit complicated. It has an expression MLINE(name,1) and a Filter ALLTRIM(UPPER(type))="USERINFO".

>>The problem only rises at times - I cannot pin down why, but all my attempts to recreate it have failed. I get Error loading file - record number 5. Baseform1 or one of its members. Loading form or the data environment : Error building key for index "C:\spm\data\userdata.cdx" tag "Userinfo". The error is not tied to a specific form, it gives me the executable line 426. Line 426 of the program that starts the application says Read Events. The lines leading up to this line are:

>>Close Data
>>Close Data All
>>CursorSetProp("Buffering", 1,0)
>>Open Data spm2000 Shared

>>I am not sure where to start fixing this. I think it is all tied to the index, but I am not sure what to fix. Can anyone point me in the right direction?
