Some Toad functionalities disappear spontaneously   when Toad is opened.  
For example sometimes it is not possible to access the tablespace view in the Schema Browser.

Whenever  Toad is started the following error appears: "Application has encountered a problem and we are sorry for the inconvenience"

Toad has been installed and uninstalled  but the problem persists.
