psensor v1.1.1 has been released.
The settings are no more stored with GConf2. Global settings are stored with Gsettings and the sensors settings in $HOME/.psensor/psensor.cfg.
It is now possible to show or hide a sensor in the main window (sensors preferences > display sensor in the list of sensors).
Source tarball can be downloaded from http://wpitchoune.net/psensor/files
The changes due to the settings management might introduce new bugs so it is recommended to use the last stable release v1.0.4 if you have concerns about reliability.
