This is not the root cause of the bug Raymond. I have explained this
several times now.

This is perfectly acceptable behaviour in PA.

I have stated the two possible solutions quite clearly (twice!) in one
of the three threads you've managed to create on this topic.

Please stop going on about the issue and please reply just once to each
email, it's incredibly annoying trying to follow any discussion you
comment on due to this deluge of responses.
