NewIcons should work with ClassAct2Demo. Did you doubleclick the "Install Classes" icon ? Did you reboot after you installed ClassAct ?
For the icon topic:
you have to distinguish the file format from the icon layout.
There currently are three file formats:
1. OS3.1 (or older)
2. NewIcons
3. OS3.5 (or better)
(4. OS4.0 will probably have its own format)
And there are different icon layouts:
1. OS3.1 standard (4 colored)
2. OS3.1 extended (more than 4 colors, e.g. MagicWB)
3. NewIcons (original icon set coming with the program)
4. GlowIcons (nicely designed icons with a "glow" effect when activated)
5. there are many more custom layouts without a common standard
OS3.1 file format holds an image with 2 or more bitplanes but without color information. Colors are taken from the Workbench's palette and might look ugly if the palette is not adjusted (e.g. by MagicWB-Daemon or FullPalette).
NewIcons is a patch for OS3.1 to support palette based icons which are rendered to Workbench's palette by the NewIcons program. There is no need to adjust the palette, NewIcons calculates the correct rendering for each palette. The colored images are stored as a special type of tooltypes. The original OS3.1 (bitplane based) image is still present in the file.
OS3.5 introduced a colorful mechanism like NewIcons but incompatible to that. Images are stored in a seperate IFF FORM following the standard icon in the file. It follows the same rules as NewIcons.
So GlowIcons can be stored as NewIcons or as OS3.5 icons. Because the Glow design was introduced as a standard for OS3.5, the word usualy refers to the file format, too. But AFAIK all GlowIcons found on Aminet are stored in NewIcons format.
