I just tried the latest daily Atari build (2105) but I am still getting the CSS Base error message.
At that point the log file looks like this : (5.875000) content/content.c content_convert 283: content file:///./hotlist.htm (0x1b1be0c) (5.875002) render/html_css.c html_css_quirks_stylesheets 503: 4 fetches active (5.875003) render/html.c html_convert 1028: quirks set to 2 (5.875004) render/html.c html_convert 1032: 3 fetches active (5.880000) atari/gui.c gui_poll 144: WM: 4944 (5.955002) render/html_css.c html_convert_css_callback 112: stylesheet file:///u%3A%5Cg%5CApplications%5Cnetsurf%5Cres%5Cdefault.css failed: UnacceptableType (5.955003) render/html_css.c html_convert_css_callback 116: 2 fetches active (5.975000) render/html_css.c html_convert_css_callback 112: stylesheet file:///user.css failed: UnacceptableType (5.975001) render/html_css.c html_convert_css_callback 116: 1 fetches active (5.990000) render/html_css.c html_convert_css_callback 112: stylesheet file:///u%3A%5Cg%5CApplications%5Cnetsurf%5Cres%5Cquirks.css failed: UnacceptableType (5.990001) render/html_css.c html_convert_css_callback 116: 0 fetches active (5.990002) render/html.c html_begin_conversion 1085: Completing parse I don't know what to try that might help.
