High CPU usage (and other issues) when folder tree locked

5.1 : Firstly, the default window was never saved, and instead it was a NOT CORRESPONDING window with absence of the TABS I had choosed to be opened by default.

How did you save the window?

How are you opening the new window?

(Which menu items or actions, and what are those actions configured to do in Preferences, if applicable.)

@Heraes

5.2 : Secondly, the CPU was highly used (~11%) with W10 lagging as hell.

If you're seeing high CPU usage with Opus, send us some process snapshots made during the heavy usage and we'll take a look.

@Heraes

Thirdly, using the BUTTON called "Saving the list as default" is systematically making an ERROR ALERT (windows' error sound) and nothing pops up. A menu seems to be hidden BEHIND the DO window, and I can't click on it, and clicking on the DO window does nothing more than replaying the sound. It's stuck, and I have to KILL the DO process.

Do you have anything installed that might be modifying other programs' windows? Anything that changes the way other programs look, or adds elements to window titlebars, or that helps move/resize other programs' windows?

5.5 My keyboard became stuck.
5.6 I restarted my computer, and my keyboard was like deactivated during logon.

There is no way that Opus could affect your keyboard, especially after a reboot and before you've even logged in.

That kind of thing sounds like a more general issue with the computer or drivers, or even a loose cable.

Whatever's causing that may be involved in the other issues.
