CAS went crazy

Hi,
I hope that everything’s gonna be okay after a restart, so just FYI. I pressed Syncronize! button and
Windows’ “Do you want to shut down/restart?” window came up. I chose cancel for 3 times at least, that Windows closed CAS and task bar CAS icon gone together with hide unused icons arrows. All task bar icons gone with the exception of CIS and Live PC Support for which I do no subscribe for and MSN.
Is it a bug?
