I am having a problem with wanikani. Whenever I answer a review with multiple meanings correctly, pressing enter doesn’t immediately get me to the next one. Instead, I have to wait for a few seconds. If I press enter too soon not only does it not skip to the next review, but the button gets deselected and I have to either click it manually or press TAB and then enter again.
The problem persists after deactivating all scripts as well.
It sounds like the Mistake Delay script, or Double Check (which contains Mistake Delay), which can be be configured to lock out the Enter button for a second so you don’t miss the fact that there are multiple meanings.
When you disabled scripts, did you reload the page afterward?
