This is an odd one. Just trying out the v12 Beta (12.0.2). Went into DO's options, and enabled 'use tab key to switch source/destination' setting. Once I did so and clicked Ok, the DO theme changed. This is what the buttons beside the path field in the lister now look like: i.imgur.com/C586wva.png
Originally for example, the up button was a blue up arrow - it's now a yellow folder with a tiny arrow on it. I checked in the Settings->Lister Themes, and there is nothing listed there. How do I get the original theme back (exited from DO and opened it again, and no change)?
Look under Preferences / Toolbars / Icons. It sounds like you have the Opus 9 / XP icon set installed and it got moved up the list above the default set.
Thanks, that did it. It's odd - not only have I never been into that section of the options (so I didn't change the order myself), I only have v12 installed - why is there a set of icons for v9 installed? Very odd.
I do note though that the default set - now that I have changed it back - is quite blocky compared to what it was. It's like it is using a low res set of icons and scaling it up. I should probably uninstall, reinstall, and then see if that Tab key setting changes the theme again...
Restart of Opus has fixed the blocky graphics. Still don't know how a v9 icon set came to be installed, or how Opus switched to it all by itself (as I say, I didn't even know that section of options was in Opus), but will keep an eye on it and if problem happens again, will try and work out what triggers it.
