Help: I4GL/C reports firing AFTER GROUP OF triggers erroneously

I4GL/C version 6.04.UC1 on SCO I have a fairly simple report (so far) I am developing. It is actually the core of a more complex system in case you wondered at the strange code. The data varies in how many of the "t" columns are actually used for ordering. The rest are constant, as you can see from the output. It seems to fire the BEFORE GROUP OF triggers correctly but then fires all the AFTER ones too. I have looked through the release notes and can see no clues. I have tried renaming variables, reordering the trigger statements and reducing the number of them. As expected, these have had no effect. Other reports I have work fine, although none exercise the feature to this extent. Am I missing something obvious? Has anyone else experienced this problem? Any help or clues would be gratefully received.

Right the AFTER GROUP OF triggers for all lower ordered groups are triggered when any higher order group changes. The solution is to protect the print statements in each section with an IF block testing on a global var or argument var that indicates if each print level is needed. Art S. Kagel
