I downloaded the latest from the repository today and found I was get an error of list.scrollTop not a function. I saw something about a dependency on the dimensions plugin. So I added that to the scripts loaded before the autocomplete. I was then getting a strange issue on the display of the results - a horizontal scrollbar suddenly appeared. This is strange to me because I never had this issue before. I downgraded to the autocomplete.min Rev 2384, removed dimensions, and no horizontal scrollbar appeared.
The reason I tried the latest revision was because in the min Rev 2384, I was having the problem of the results set changing (it would return the correct results and show them, then it would suddenly show the results based on the last character typed being removed) like this: enter: carp briefly shows: Annette Carpenter Alex Carpel then that result set is replaced with Joel Carmen Tiffany Carson etc...
