HTC Desire S :: Interface And Apps Restart After Pressing Home Button?

I've been running my Desire S for about 6 months now. Just about set up how I like it. nnoyingly it has developed a problem where after playing with any app and pressing the home screen, 9 times out of 10 I get the white background with green HTC logo, then a "Loading..." message over the home screen. When I go back to the app I was *just using*, it acts as if I've opened it for the first time and forgets where I was, what pages I was on, which album I was currently listening to etc.I've tried a few things suggested by the Internet: - Restarting the phone (of course)- Removing all widgets from home screen in case one of them has crashed- Checking I am not regularly running out of ram- Checking I am not dangerously close to running out of iternal storage- Unmounting the SD card- Un-installed any app I've added in the past month- Checking none of the app icons have become duplicated on top of each other (??? hey I was getting desperate)I have also been keeping an eye on the Services tab but to be honest, things seem to restart so often in here that it is hard to identify which one is acting out of the ordinary.

I took this into the t-Mobile shop, explained that I know they are not HTC tech support but that they might have seen the issue before and have a bit of a clue with the phones they sell, explained what I'd done above and they came back with the most unhelpful of default cop-out answers: "Software update."Latest Android version available through t-mobile is 2.3.3 which I am on.TC Sense is at v2.1oes anyone have any ideas? I would really rather sort this out without having to factory reset my phone. Firstly as I had my phone pretty much set up how I wanted it, secondly I have so many apps for which I have no idea how to reliably transfer their saved info (mostly music creation apps with their own save formats/locations) and thirdly so that I know how to resolve this when it inevitably happens again.
