Yes it's a problem with can happen when DBF file is corrupted
not MEMO one and application tries to access memo field.

And this message is also confusing because it reports error
in FPT file when the problem is in memo block address stored
in DBF file . It contains repl(" ",9)+chr(10) - Clipper decode
it as number without any validation and this as result it
receives some unexpected block number
I'll add valid RT error message ASAP.
