I am doing the same and works, but then I was thinking that's it's probably best doing at the beginning, with a clean UI. I thought that doing it at the end, before closing it, would then fake a reload of the app in the state it was left when closing it. But this has an issue, which I think deserves thoughts: 1) to really speed up things you should take the screenshot only once. 2) if you do it at the end, before closing, for the reason above, then you've got to take the screenshot at every exit. This slows down the exit itself. And this is as much of an issue as the startup speed. Thus I thought I'll take the screenshot at the expose event and only take it if the file is not there already. -- anidel Sent from London, Eng, United Kingdom _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
