Bug 30344 Insertion of 'scrapbook' error messages unhelpful
When an error occurs in the scrapbook (e.g. a syntax error) or a result is returned, the scrapbook inserts text in the scrapbook page (which is what VAJ used to do). This has always been remarkably unhelpful; if the developer does not delete the message/result straight away then when selecting a block of text next time may end up with the error message being interpreted, which gives a further error message ad tedium. It would be much better if a pop-up-dialog box was used to indicate of a result/error that could be dismissed leaving the source code intact, or alternatively displaying the result using another mechanism (pop-up text, console for standard output/error etc.)
