I’ve updated Emerge to version 1.3.1, where I’ve fixed a couple of bugs. One is related to the display of the spinner. The other, to console errors when using CSS images. If you aren’t bothered but these, there’s no need to update.
If you’ve bought Emerge, you get the updates for free. Just re-download using the same link you got when you bought the script. Or drop me a line if you have any questions.
