The rapid start function makes CS+ permanently resident, to accelerate the startup time.
You can enable or disable the rapid start in the [General - Startup and Exit] category in the Option dialog box, with option [Reduce startup time by enabling rapid startup] (Default: enabled).
When the rapid start is enabled, after login to Windows, CS+ is in the standby state, and the 
icon appears in the task tray.
To release CS+ from the standby state, and display the Main window, select [Start] in the context menu of the 
icon, or double-click the icon.
Click the 
button on the Main window to return CS+ to the standby state (an 
icon is displayed in the task tray during standby).
