Hello,
I am using a custom list to sort data (more than 255 characters). My problem is that when I reopen the file I get the error message:

"Excel found unreadable content in "File name". Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes."

When I recover the data the only thing that changes is that the sorting filter is removed from the Sort window. This is from the report:
Removed Records: Sorting from /xl/worksheets/sheet18.bin part
It makes no difference if I create the custom list from File->Options-> Advanced -> Edit Custom Lists, or with VBA. Is there a way to fix this error?

Thanks,
Antonis
