I'm running gingerman 6.5.1 on a Ideos u8150 phone. Well there is a small problem with application switching. For example if open YouTube app and search for video and switch to browser and after few seconds if i switch to YouTube app again the YouTube app the search result are not there, instead it shows me the first YouTube screen. This happens with some other applications such as Opera Browser as well. Seems like after few seconds the previous app is being killed or kind of hibernated. How can i disable this behavior ?
