%execute[%EXEC ... ] broken?

[mr_F_2]

I added the following to my UserInfo file in \text\ftp :

| Last seen: %[execute(%EXEC ..\scripts\ioSeen\ioSeen.exe)(v %[$user])] |

executing it manually yields:

C:\ioFTPD\scripts>ioSeen\ioSeen.exe v a_users_name
on Sun Sep 05, 2004 at 17:04:02

it doesn't like the %[$user] so it outputs this:
[L] 200-| Last seen: )] |

could this be fixed?
