Tony, that is ok, about people staying confident with the app of their choice, upgrading it was a suggestion that may work or not...
I personally use X3 and have never encountered that problem...
on the link you provided, the OP did not return yet to give information if or what worked or not... I am assuming that there are conflicting apps installed or the OS is not in a stable state (may appear to the casual user as if it is), e.g. not up to date etc...
