 Well, as has been pointed out, you can run programs with an option to
install a private colormap (e.g. '-install' for Netscape, '-colormap 
Private' for ImageMagick) and you won't see this effect, but your colors 
will do psychedelic changes when you switch between applications.

 I personally sprang for the extra Mb and run in 16bpp now. It's very 
nice, and .jpg images are more colorful, too. (GIFs only hold 8 bits of 
color information - JPGs hold a lot more, 24 bits or more. So if you can 
display more than 256 colors they often look noticeably better.) My video 
card (Diamond Stealth 64 Trio64) also got noticeably faster, though this 
wasn't an outrageous improvement.
