Hello,
After upgrading to 9.93, if you click on "computers" for example in the JSS, and then click "new" button under advanced computer searches before the page is actually completed loading, the "New" button will become un-clickable until you load the page again. You are able to click other buttons while in this state. And if you refresh the page, and make a point to not click the button, it will become clickable again.
NOTE: This is not specific to the "new" button, it seems to be any button in the JSS.
