It seems to me we're going to get an awful lot of questions like this. It seems reasonable to have a set of stock steps to take for misbehaving apps.

I suggest that [my answer to one such question][1] would be a good start.


Steps to take with apps that just aren't working properly is:

From Settings | Applications | Manage applications | <application>

   * Force stop

if that doesn't help

   * Clear cache

if that doesn't help

   * Clear data

if that doesn't help

  * Restart the phone (turn off/turn on the phone, unless you have a "restart" option)

and if that still doesn't help, try the nuclear option:

   * uninstall and re-install
