What happened to the wix editor? Why isn't it working properly?

Hey all,

So I've made wix websites before, but haven't in like 6 months or so. I wanted to update my website by creating a whole new layout. The problem I am having now is: nothing works properly. I try to change the font size, nothing happens. I try to reposition text, images or anything else, and nothing works properly. I often times can't even click and drag anything anymore. Fonts will often times not change when I change their font or size. When I try to reposition images, it will suddenly just jump to a whole other part of the page and then making me unable to change it back by dragging. Just now, I was resizing a text box using the ball-knob things, and the complete section (where the text is in) just resized and cropped itself into something I totally did not do. All sorts of things like this.

It's highly frustrating.

Am I doing something wrong? I tried using different computers, but I'm still having the same problems. I'm literally open to the idea I am maybe doing something wrong. I have quite a lot of experience with wix, and have never had any of these problems before. I used to love wix's workflow, but now I'm struggling for hours with the most simple things, which is unfortunately making me contemplate moving to another website builder - which I honestly do not want to do.

Very curious to hear any of your ideas.

Thank you kindly.

Also: why, when I upload high quality images, so they look to blurry and pixelated when added to the website?
