I have some report generation code that has worked under VFP7 for years, but now gives me an "error building key for index [cdx filename] tag [tagname] under VFP9.

the code pointed to in the debugger:
index on iif(eof('PERSONEL'),EMPNO,PERSONEL.SNAME+PERSONEL.FNAME)+dtos(date)+DUTYTIME+EXCCODE tag REPORT

If I suspend the program and then immediately resume, the error disappears. I assumed that it may have been an issue with data in memory not yet written to disk, so I added a flush command - no luck, neither did a wait statement.

If I run the same process in VFP7 there is no error or issue.

I'm using XP SP3, 2Gb RAM and a 2.7Ghz CPU.

Any suggestions would be very welcome....
