RerunErrorsUntilAllCorrect

[David McFarlane]

I did not look at your attached file, but here are a few hints to 
consider.  Instead of Context.SetAttribAtSource, try the more direct 
List.SetAttrib (n.b., I have had trouble with SetAttribAtSource 
myself).  You may also adjust List weights at runtime with 
List.SetWeight.  You may have to do a List.Reset to make these take 
efffect.  See those and related topics in the E-Basic Help facility.

Finally, you may find the "Study Recall" example at the PST website 
relevant to your task.
