I often go through cards in Browse and make new ones in Add based on stuff I’ve copied and pasted from Browse, usually from the Front of some card. Whenever I go from Add back to Browse to copy something from the Front of the next card, Anki remembers what part of the string I copied from the previous Front and automatically highlights that part of the string on the new Front.
This is highly disruptive of my workflow. It didn’t happen back when I used 2.1.40. It only started happening when I got a new computer and was forced to update to 2.1.65. (I would just revert to 2.1.40, but my computer won’t let me.)
Could you please add screenshots to illustrate your issue? Maybe it is just that you activated the feature to make fields sticky: Adding/Editing - Anki Manual
Sometimes the auto-highlighted text is what I would highlight anyway, but sometimes it’s not. Either way, I find it more difficult than having nothing auto-highlighted.
At the top right of the Front field, you can see the < > icon. When you click it, it should open up a second input field immediately underneath the existing input field, and this new field will display HTML tags.
Does it show anything like 1 cat<span text="red" bgcolor="blue"><sup>ACC</sup></span>
or similar tags?
If so, the auto-highlighting might actually be part of the content of the field.
Yes, the light-blue background is not there inherently, it’s just that that substring is automatically selected because Anki somehow remembers what I selected on the previous card. Clicking anywhere in the Front field deselects that text, so it’s not a major problem, it just throws me off and isn’t like what I grew accustomed to from 2009 through earlier in 2023.
These are my add-ons:
Browser MaximizeHide TableEditorSidebar (not sure what this is, don’t remember why I have it)
Customize Keyboard Shortcuts
Hide editor elements by id class CSS selector (not sure what this is, don’t remember why I have it)
Scale images
2 and 4 in this list are very important, and I had them long before this auto-selection thing started. Maybe I’ll try deleting 1 and 3.
