I have finally updated my modified roundcube view to work with the 
latest CVS release.  Additionally, I have modified the taskbar icons so 
the text now displays below the icons instead of beside them.  These 
skins work without errors on resolutions down to 1024x768, but 800x600 
is still not supported (and won't be supported until the "move to" drop 
down box can be gotten rid of).
    This skin is tested on IE6 and Firefox and should be working without 
error.  To install, simply unzip this file into your skins directory, 
and then set $rcmail_config['skin_path'] = 'skins/modified/';  in 
main.inc.php.  This will not overwite your default skin, so you can try 
it at 0 risk. 
    To help things display better, I recomend you make the following 
changes in roundcubemail
program\localization\en\labels.inc:
$labels['settings'] = 'Settings'; $labels['addressbook'] = 'Contacts';
This shortens the labels from Personal Settings and Address Book.
Enjoy, and if you have any comments or suggestions, please email them my way. Rob
