Since moving to Foxpro 8.0 from 6.0 we getting a strange error about once every month or two. The error occurs on the [Seek 'b'] command and the error message says 'Record not locked'. While its true that the record is not locked, the fact is there is no need for it to be locked at this point =)

There are no relationships established. The program does not use record or table buffering. For the life of me I can't figure out what is going wrong.
I would appreciate any ideas anyone has about what might be causing this.

priv m.tempz,savefilt
set exac off
store filter() to savefilt
set filt to
m.tempz=order()
set order to tag blank
seek 'b'
