This (very simple) gui app :

GUI_APP_MAIN
{	

	int pid;
	pid = fork();
	if(pid > 0)
	{
		PromptOK("Process " + AsString(pid));
		return;

	}
	else if (pid == 0)
	{
		PromptOK("Parent Process");
		return;
	}
	else
	{
		PromptOK("ERROR");
		return;
	}

	TestFork().Run();
}

Crashes (with memory leak msgbox) instead of forking into 2 processes.

Eh, I wish I knew all details that can go bad when forking GUI process. Anyway, for starters, there is socket open to communicate with X11 server - wonder what happens to that Smile

Well, I would have been happy to fork and close the parent (that was what I needed...) but doesn't work either.
I guess the fork() must be done BEFORE the gui initialization.

The strange stuff is that SysExec() package USES the fork() and it works....
