I have been using Signage Studio Pro v6.2.22 for some time now. I have noticed that changing the duration of an item in a channel does not adjust the time consistently.
If you select an item in a channel and adjust the duration by 1 second (say from 10 to 11 seconds), it will change that item's duration as expected (the value in the spinner changes, and the item in the timeline changes width). Then if you select another item in the same channel and change the duration by a second (again 10 to 11 seconds), the spinner value changes but the item width does not. If you select another item and go back to the previous one, the duration is the original value (10 seconds).
The same goes if you key in a duration value. Sometimes it will change to the new duration (regardless of the value), and sometimes it will not.
Most the duration changes I make are usually 1-2 seconds, so I have gotten into the habit of incrementing by 2 and de-incrementing by 1 (and vice versa for reducing durations).
Has anyone else experienced this?
