The service packs have generally been good on my TP, but not so this time. After the 3.0.4, it starts acting laggy and unresponsive after running several days, including
- takes forever to complete loading an internet page.
- often refuses to respond to presses, even though the screen brightens in that area to show you that it got the press.
- has lost data. All my downloaded Time magazines disappeared, necessitating redownloading.
- the screen darkens and lightens on it's own, for no apparent reason.
It's basically like it's doing something else in the background. The only thing will makes it better is to restart it.
Unfortunately, even THAT'S a problem! It ignored my pressing and holding the restart/power button too for several minutes until I finally got it to do it.
