>A page header doesn't print if all that's left to be printed is the summary band. Sergey thinks of this as 'by design'. I disagree.

There's easy workaround. Create report group on EOF() and move Summary Band fields into its footer.

>A group header occasionally doesn't print. There seems to be a certain pattern, but it's not easy at all to control that pattern. We both think of this to be a bug.

The one case we discussed happens when group footer is orphaned. It can be "cured" by preventing orphaned group footers.
