Whenever I try to open the messaging app (text messages and email), it does not open but everything on my phone starts running really slowly. I checked with Dot Fred's task manager and see tmail.exe taking up all the cpu. The only way to get things normally again is to turn off the phone and boot up again.
The first time this happened was when I received a text message and pressed reply in the menu. Now it happens every time I try to open the app.
Can I fix this without hard resetting and having to restore everything?
