Bug in 7-day Week View - Outlook 2003?

Can I ask other folks here to try this one...

I work shifts so my working week is effectively 7-days and I also happen to
prefer the "look" of the WORKING WEEK view with the appointments showing as
vertical time lines... I have noticed that IF the working week options is
set for all 7 days and I then switch to the 7-Day View (using the button on
tool bar) then the display seems to be corrupted... only if I click the
up/down buttons to advance the dates shown will the display be re-drawn
correctly... the other workaround is to click on the MONTH view FIRST then
click on the 7-Day view - it is really strange. If I set my working week
options to display LESS than the full week - i.e. Monday-Friday - then the
problem goes away ---why???
