When using Redbrick Cloud, if an application crashes such as Adobe, Outlook, or Redbrick PM itself, sometimes the easiest way it to force close the application and re-open it. 

You might be used to, on your local machine pressing Ctrl+Alt+Del to open task manager, but as this will open your local version of this, within Redbrick Cloud, instead right click your tool bar (or windows icon) and select "Task Manager" (if you do not have access to Task Manager, the quickest alternative may be to log off and back on again)

Right Clicking the Toolbar

Right Clicking the Windows icon;

Once Task Manager is open right click the misbehaving application and End Task
