I have a FM db that is a few years old, last year we upgraded to FM13 Pro/Server with no issues. In just the last month I have accumulated 7 blank records in the db. Attempts to delete the blank records are unsuccessful however I recently noticed that I can search on criteria that would have been in the deleted record such as the auto assigned ID number and the empty record is returned. The same search on a fictitious number that doesn’t exist gives the expected no results found. Has anyone seen this type of issue?
I've seen something similar. I suspect a damaged file. Take a recent download (assuming that your file is in regular use over a network), and recover that copy. See if the recovered copy still has this problem.
