In the Jobs view, you can’t expand the Interval/schedule column to see it all.
In the Next Date (below the Jobs list after you create a job), in the Time field, if you click on a time piece (hour, minute, or seconds, then click the up or down arrow, your item loses focus. You can only increment it one at a time. It looks like the focus goes over to the checkbox. This works fine when you go through the Wizard to initially set it up.
For the Repeat Interval, is it possible to pop up a dialog box like there is in the Wizard? After you create a job, you may not have an interval to begin with. Then you might want to come back later and add one.
