I understand the problem, have been bitten by it sufficiently when working on AM. But is there a way to display some side-effect so that the developer knows that 'something' has gone wrong? A non-modal dialog box giving some info?
Yes. The way to do better is to render in a bitmap, then to display the bitmap. This is what I do with the non popup nodes with the bitmap cache. This is more a matter of available resource than technical challenge to make this happens.
