Hi David,

Many thanks for your reply - I didn't know about the EXPOSE_EVENTS or RETAIN options for my draw widget. I was setting RETAIN=2 in the IDE preferences, not in my draw widget.

I have now switched on EXPOSE_EVENTS and have set RETAIN=0 in my draw widget, and changed the event handler to deal with the expose events that are generated. Everything is working well.

Regards,

David
