Hello,

one (and only one) of my tables is only sortable by the primary key
field in ascending order. Trying to sort the key field in descending
order or to sort by any other field of the table results in the
following message:

ISC ERROR CODE:335544344

ISC ERROR MESSAGE:
I/O error for file "%SystemDrive%\temp\ib_sort_a00168"
Error while trying to open file
The system is unable to find that file
Sort error

All other tables of my database can be sorted without problems.
The table has 4950 rows.
The directory %SystemDrive%\temp exists and I have 157 MB free space
on that drive.

Any help appreciated.
Thanks,
Mario
