I made a few duplicates of my theme at http://www.elizabet.nl/wordpress.
All duplicates show correctly in the administration panel, different titles, different folders, different descriptions, etc.
However, only the old theme shows up, regardless of which theme dupliacte I activate in the administration panel.
Also in preview mode, every theme duplicate shows the original theme.
Themes are pretty much the same, just some minor differences. Headers are different.
Original theme (header):
/*
Theme Name: New Theme 1
Theme URI: http://www.elizabet.nl
Description: Template
Version: 1.0
Author: H.M. Vos
Author URL: http://www.hannemaatje.nl/
Tags: black dark jugendstil
*/
Duplicates (headers):
/*
Theme Name: Elizabet 1 AJAX
Theme URI: http://www.elizabet.nl
Description: Met AJAX implementatie, zonder content background graphics.
Version: 1.0
Author: H.M. Vos
Author URL: http://www.hannemaatje.nl/

/*
Theme Name: Elizabet 2 AJAX
Theme URI: http://www.elizabet.nl
Description: Met AJAX implementatie en content background graphics.
Version: 1.0

Any help is greatly appreciated! Hannemaatje
