A few nits about icons...
On Linux, running the mwm window manager, when I minimize AbiWord and
get the stylized "A" icon, the transparent parts of the icon aren't
clickable. It's a very sparse icon, pixel-wise, so it takes some
careful aim to hit it in order to maximize the program. Whether this is
a gripe about mwm or AbiWord, I'm not sure. NT makes the internal part
of the icon active.
On Windows NT, I'm using the "Swimming Pool" backdrop. It's a very
similar color to that "A" icon. I often lose the icon on the screen. I
notice that the Internet Explorer icon is about the same color, but it
has a border outline that's a contrasting color, and that makes it more
visible on a wide variety of backdrops.
