>When trying to save a new record through a "save" button within my application, the user got the following error "Internal consistency error", then a windows application error message that says"The instruction at "0x0c001b28" reference memory at "0x000000". The memory could not be read".
>This error is not machine-specific. The error was fixed when I deleted the last record from that table.
>Now, the error returned for the user, so when running the application from the "application production location", I get the error. But copying the data to my home directory,and saving a record does not bring any error.
>Any suggestion on what might the problem be??

Most likely an Index. Try rebuilding the index tags.
