Converting forms to 2003 format

[GaelicFatboy]

I've got a database with forms originaly designed using Access 2000. I've converted the files to 2003 format using the tools menu, but the look and the layout of all the controls are as the 2000 format and not the newer looking 2003 format.

Is it possible to convert these 2000 style forms to the 2003 style?

Cheers
