Opera Browser

Does anyone else have a problem when using Opera on chess.com that when you try to click through a game (on the small game diagrams, such as in articles), it just goes haywire, with a menu popping up next to the cursor on pretty much every click? Very annoying, would love to know of a way of fixing it (preferably without using another browser).

Which version of Opera and is it on a Mac or Windows?

It's version 10.61 running on Windows 7 (had same problem with the same version running on XP as well).

I'm with you, it looks awful in Opera - no background just a big ball of blazing whiteness.
