On 9.06 Ginan, reading HTML and CSS Mode Help is not possible: some fonts have no colour at all, some are yellow. This only occurs towards the end. The start is ok, though.
I see this after opening an HTML file, going (under the Alpha Menu) to HTML Mode Setup -> Mode Help.
The window starts well, but the end is unreadable.
Thank you for reporting. I can see this.
After investigation, I don't see what may have caused this: somehow the file has been damaged. I have recompiled it (from its aida sources) and everything is back to normal.
I have uploaded the corrected file to Alpha's web site:
