I am on an openSUSE 11.1 laptop and have just installed Opera 10 and everything runs great except composing messages with HTML in Usermin... the HTML editor does not appear.. and I have to write the HTML message with tags in the space that shows between the HTML and BODY tags, to get a message sent with HTML.
Ther's no problem in Firefox.
An HTML editor does appears in other webmail like Yahoo to 'Compose' .. so I am assuming this is Usermin specific with the Opera browser.
Anyone else with this issue?

I haven't heard anyone else
I haven't heard anyone else commenting on that particular problem -- but if you continue to see issues with Opera, I'd recommend filing a bug report using the Support link above.
