Timings Tab

Shutdown Timeout	In order to give it a chance to close gracefully NT Wrapper sends either a WM_CLOSE message to all top level windows of the application or key combination/signal "CTRL + C" to the process. If that fails or the specified Shutdown Timeout has expired the application is hard terminated. "CTRL + C" is only sent to console applications. The Shutdown Timeout is distributed among the application and all its child processes (see also: Tab Enhanced).
Launch Delay	Delay before an application is (re)started.
Execution Time	If > 0 this value specifies the amount of time the application is expected to run for in milliseconds. If this time limit is exceeded NT Wrapper will close the process regardless of what it is actually doing.
