Hi SkipBNA,
A suggestion that has been made before in this ng is to add a task with a
duration of 1 min as a predecessor to the task in question. Then create a
calendar (Tools > Change Working Time > New....) In the new calendar click
on the M column heading to select all Mondays and edit the working time to
7:58 am to 7:59 am. Click and drag to select T through F in the column
headings and make those days non-working. Then double click on the 1 min
duration task and assign the newly created calendar to the task (on the
Advanced tab of the Task Information dialog box.) This should force the
predecessor to only occur Monday morning with the successor task scheduled
to start immediately after.
Hope this helps. Let us know how you get along.
Julie
