Sorry you are having an issue. As noted, when you go to any screen, the first record is auto-selected. However, since you have to right click on a job to either run it or hold it, they have to actually be placing the mouse on that first job to get those results, as in there is no keyboard shortcut that could be doing this. Perhaps they are thinking the highlighted job being 'highlighted' is the one they need?
Unfortunately, there is no way to remove that selection of top job at this time.
