Needless to say that when we created XMLmind XML Editor we didn't imagine that such use cases could happen. Sorry for this shortcoming. > when opening large docbook files.

Solving this problem is not easy. Ideas: * Make image toolkits support background rendering of images (like in a browser). * AND/OR Let image toolkits generate a low-res image (a .png file) the first time an image is rendered and then use this low-res image for subsequent renderings. In all cases, this requires deep changes in the image toolkit plug-in framework.
