I believe I know what @Farmer is saying - when you switch the TV (non-Roku) source from the HDMI input where the Roku is connected to another source the Roku returns to the Home Screen. It used to remain in the channel/app and still streaming if it was streaming before the source was changed. I've seen similar complaints, but I don't think there's any way to prevent that from happening. Whether it is model specific or specific to some firmware update I couldn't say.
