Off line Win10 PC, but cant say who might be coming into the house whilst I’m out walking the dog, but I know people have been in the house in the past and wiped my backups drives.
All of a sudden a browse box doesnt want to scroll past the visible records in either direction.

If I click on one of the column headers as I have column header sorting enabled, the up and down and page up and page down buttons work.
Its on a key with two elements which total 2052 bytes in length, so by clicking on the column header is removing the key from the equation.
