In the maintenance plan with multiple tasks linked by a constraint without a scroll bar, the tasks cannot all be seen and there is no scroll bar. When the constraint is added, the second task jumped to an "off-screen" position.
Software defect
WORKAROUND 1:
Use "Ctrl+down arrow" to jump to the seond task.
WORKAROUND 2:
For the invisible second task in the LiteSpeed maintenance plans, if you click your mouse on the Design screen, but below the list of tasks, then Ctrl+down arrow, then click back in the main area of the design window, the screen will adjust to the second (lower) task and you can then click and drag it back up to the upper portion of the screen.
STATUS:
Fixed in 6.1.1 version of LiteSpeed.
