I ran into that same problem. My crude, misinformed understanding is that RHP purposely displays
differently depending on whether you are running Netscape or Internet Explorer, and that (maybe)
anything not IE is treated as Netscape. Not sure the need for the different displays, maybe something
buggy in the way Netscape worked????
However there MAY be a workaround for you:
For one of my current browsers the workaround was to change the "browser identification",
(apparently how it ids itself to websites) to Internet Explorer 5.5 on a Windows 2000 machine (It's
really Konqueror on a Linux box). This got rid of the radio buttons and returned RHP to the nice chess
set and let me use the browser I wanted.Yeah!
You may be able to do the same in Opera; according to their website, and I merely quote:
"you can also experiment with your "Browser identification" setting in "File/Preferences.../Network".
Change the "Identify as..." "
With my browser, there were a variety of choices of IE versions and Windows OS's to choose from;
for whatever strange reason, only the above combo worked for me...Point is, if one setting doesn't
work, try another.
Let me know if it helps...always curious if my suggestions ever work....probably not 🙂
