There is a bug in the 2.2 version of the ThemeStudio. When I try to create the Idle Screen, I tell it to use white for the idle font color and black for the softkeys. However, when I try the theme on my 6288, all fonts are white. This makes my phone unusable, as I use a plain black background as a bg image (I like simple stuff so I don't use multi-color images as bg) with a white banner for the softkey bg. Basically, this bug, makes my phone to render the softkeys as white font on a white background, making it unusable.
Download the theme from here to see the problem:

It looks fine in the ThemeStudio itself, but not on the 6288.
