I suggest that VarAC setup included the capability of launching other program after starting, (and shutting down prior to closing).
Setting options might include:
-Full path to the executable
-Start program on VarAC start - Checkbox
-Close program on VarAC close - Checkbox
-Delay action in milliseconds
-Ordering if starting multiple programs
-Provisions for any parameter to be passed
My use would be to auto start DXkeeper (logger) since it appears that DXkeeper must be running in order to accept a new log entry from VarAC.
There may be other uses as well.
