I have seen this sort of problem on another app where the problem was
to do with whether a scroll bar was required or not. The s/w was
deciding that a scroll bar was necessary and then after adding the bar
decided that it was not necessary, or something like that anyway.
I don't know whether this is the situation here but just suggesting it
in case it helps.
