Very helpful! Looks like it was related to the actual time the predecessor ended. Before I posted, we had already selected the date/time format in Options to see that the task was starting at 1700 on Friday instead of 0800 on Monday. Based on your suggestion, I created a task that ended on Friday and had a successor starting on Monday. When the Friday task had a full 8 hours planned, the successor started at 0800 Monday without showing the Gantt bar running through the weekend. When I changed the 8 hours to 6.5 on Friday, the task ended at 1530 on Friday and the successor started at 1530 on Friday and the Gantt bar ran through the weekend. Much appreciated.
