There are the two minor changes you need to make to avoid this problem, part of
which has to do with backgrounds. Note to long-term users: This problem will
occur again in 2001 and 2018 and every 11 and 16 years afterward:
In the DateBook's stack script, change the "goweekly" handler from this:
set lockScreen to true
find startOfWeek(myDate) in bkgnd field "WeekSecs"
To this:
set lockScreen to true
go bg "Weekly"
find startOfWeek(myDate) in bkgnd field "WeekSecs"
Also, in the stack script, change the GoSixMonthly handler from this:
visual effect zoom open
find thisHalfYear(myDate) in bkgnd field "MySecs"
To this:
visual effect zoom open
go bg 1
find thisHalfYear(myDate) in bkgnd field "MySecs"
These changes will solve both the problem of not going anywhere when you click
on the first week in January and the "can't understand bracketweek" message.
