The today menu stuck.

The today menu right beside the notification menu is stuck and the demo videos for the different thing you can do with a macbook trackpad in the settings are also frozen... i am using an early 2014 macbook air with mac os high sierra 10.13.1.. this problem isnt because of high sierra because it still persisted when i was using yosemite... can anyone please help? switching user accounts also makes it work but it never works in the admin account..
