A program running in a TaskWindow is always a task.

Since ProgA is running in a TaskWindow, that question does not make 
any sense.

I cannot see why that should make any difference. Each executable is 
in some directory or other. Whether it starts with a pling or not is 
only relevant to the Filer, not to program environment.

Yes, there is. Starting progB directly from ProgA would replace ProgA 
by ProgB, i.e., ProgA would be terminated.
