While I tried to uninstall one widget on the 5800 handset, at the same time, the 5800 received one SMS. so I am not sure if the widget has been unstalled successfully.

Then while I go back to the "Applications" menu, I find ALL the widgets can't run but Symbian applications can run.
and I go to the Application Manager, in the list of "Installed Applications" also has not ALL widgets, only Sybian.

For now, I can't install any widgets to it or run any widgets installed on the 5800?

Does anyone know how to fix it? Thanks
