[Plugin: Multiple Category Selection Widget] Broken

I have been using the plugin for nearly 2 years.
tried updating to the latest version about a year ago and it just stopped working so I had to download an older version and re-install it. Haven’t upgraded it since then. I currently use version 2.2.2 which seems to work fine (I am on WordPress 3.3)

?? thanks so much , I found a download of 2.2.3 and it works.

(My temp workaround was mysite.com/category/cat1+cat2+cat3 , slugs have to match cat name.)

I just downgraded. Did either of you figure out a way to add back in the “reset” button?
