UNIQUE and INDEX keys should not both be set for column `ID_TOPIC`

[Niteblade]

SMF Version: SMF 1.1 RC2
(Shared hosting.)

Through phpmyadmin, I goto my database.

I tick off All Tables, then run a "Check Table" on them.

Here is the result ... everything gives a msg_type of "OK" except for "smf_log_floodcontrol" which gives a msg_type of "The storage engine for the table doesn't support check"

There is only one message at the bottom ...

Problems with indexes of table `smf_messages`
UNIQUE and INDEX keys should not both be set for column `ID_TOPIC`

Does this represent a problem or a conflict with one of my mods ? I know that one badly structured mysql query can slow the entire database down.

What should I do ? Leave it alone ? Change it ? Modify it ? (Modify it to what ?)

This is not a problem and is intended, phpMyAdmin doesn't seem to understand that there are times when people might want more than one index on a column.
