Hi flash japh,

Thanks so much for your response.

I guess it's possible that this is the case, but if so it's outside my remit and I'd have to post it to the wxWidgets website. The destroy is handled automatically by the underlying wxWidgets c-code. wxPreviewFrame works fine with a wxPrintout object but not with a wxRichTextPrintout object - or at least my version of it.

I guess I'd have to write a test to prove that your theory one way or the other. ANy ideas how I might do this?

Thanks again.

Have a good day.

Steve
