On every stable version 5 released, I have automatically updated. I think only 1 version had problems.
And everytime I did automatically updated, I found that the version seems to have minor issues. (ie:- non-stop analysing of DVD, DVDFAB hang, Burn problems).
However, if I uninstall the older version & clean registry and install a new version, (without updating) the problems disappears!!!
I bet most issues can be solved this way.
