I have been downloaded the files and have been able to reproduce the error.

I have also been able identify the line of code that causes the error.

However, I have not been able to identify the circumstances which cause this line to fail for this one class only -- but not for all the thousands of other uses of PEMEditor.

(sigh)

This error can be reproduced outside or PEMEditor, once you have done Modify Class:

ASelObj(aObjects,1)
oObject = aObjects(1)
Amembers( laLines, oObject, 3 )
