The whole point of buying a Symbian OS smartphone like the 9500 is that its multitasking lets you keep loads of things running at once. Starting up applications takes three seconds a time, so you don't want to be doing this too often. Make sure you don't keep closing programs down with 'Exit' (unless you're sure you're not going to need them again). Instead, simply use the left-hand menu card to switch to another running program or use the main application shortcut keys or press 'Desk' and choose a new one.
