SpawnProcess fails when console is hidden

[Nemo]

Hi,

I have win32 program, which takes command line parameters and 
passes them trough socket to another program, running on the same 
machine. If connection fails, it needs to start the another 
program.

I don't want console to popup so I added "-L/SUBSYSTEM:WINDOWS". 
This works fine, except when it would need to start the another 
program, which fails silently. And I guess because console is 
hidden, no error messages or exceptions appear if I try to run it 
from console. Removing the linker directive makes spawnProcess 
work. To make this mysterious, when I run it from eclipse DDT it 
works all the time...

The starting happens in catch:
} catch (SocketException ex) {
    spawnProcess([`c:\Progra~1\XXX\YYY\program.exe`, recipe]);
}

I am all out of ideas, so all help is appreciated.
