HoverWare text objects do not render correctly on Linux (not sure about other OSes). In the simple Welcome demo (spinner class), Text objects specified in a .txt file appear to parse correctly, but do not render correctly. If HW_OPT_USE_DL is specified, all the surfaces (back, front, side) turn out white. If the opt level is not specified, surfaces appear to respect color, but not texture.
Talk about an old bug... :-)
