Check this out, tell me if you get the same results.
I use Advanced task killer (free)
- kill all my tasks
- Check them, all closed
- Open sportstap, touch home button
- re-open Advanced task killer
the following are now open
- My Coupons
- MixZing Lite
- Sportstap (the only app I opened)
- Mototourch (LED not Lit)
- Messageing (should open by default)
- Advanced Task Killer ( I opened this one)
My memory does from 71M to 46m when all those apps open.
I tried the same routine as above replacing Sportstap with other apps.
It does not happen, no other apps open.
