This reply made me curious and I would be grateful if 
somebody can provide some background and help me to understand: What are 
possible reasons that non-native controls "eat some of the low evel 
events"? Why should I never try to use events which are a documented 
capability of a control? Shall I regard it as normal that I can only 
access an event if I add additional code as proposed by Bruce? I am 
asking this, because I program controls myself (beginner level) and so 
far didn't have the experience, that events fail - unless I forgot to 
raise them. Best regards Claus /
