Form Upload - White background on 'files' list.

The following information is required to get an answer:
Get this information from the PHP diagnostic (in the configuration wizard).
Gallery version: 1.5.2-pl2
Apache version: 1.3.34 (Unix)
PHP version (don't just say PHP 4, please): 4.4.1
Graphics Toolkit: NetPBM
Operating system: Linux
Web browser/version (if applicable): Firefox 1.5.0.1 Mac

When using the Form Upload Method to add photos - the files list (local root of image to upload) displays over a white background. Since my popup body uses white text - white on white is no good.

Is there a way to override the background (or font) color settings for the files list?
