utorrent acting querky intermittently

I have used utorrent for over 2 years and have kept up with the upgrades. I never had a problem with the software until I installed the portable version when it was introduced.
As I did with the non-portable version, I choose to redirect the new downloads, the completed downloads and the torrents to separate folders but this is creating occasional weird intermittent results.
It sometimes,
. restarts the torrent even when it has completed and left for seeding. A couple times it splits the completed folder between the new download and the completed folder.
. changes the location of the completed folder to the new download folder, forcing me to change the location back and do a forced recheck.
. On rare occasions when I am forced to do a force re-check, it calculates a few files as incomplete while 99% on the files are determined to be 100% complete.
. a couple of times, newly added torrents would disappear from the screen when the program was re-opened forcing me to re-add them again.
. changes to priorities to some torrents would return to the previous priority when re-opening the program
. just go a new problem that returns 2 torrents entries in the completed display even though the completed file and torrent have been removed using the software option.

I had the problems with 1.8.4 and 1.8.5

I have been downloading torrents practically none stop using the port app utorrent.

Again, I want to stress these are intermittent occurrences but a pain in the royal a$$.
