The problem is in GrClose() in the client. Edit the file
".../microwin/src/nanox/client.c". Look for GrClose(), add the line
"nxSocket = -1;" to the end of the function. Then all will work well. ie:
CHANGE THIS:
void
GrClose(void)
{
#if GR_CLOSE_FIX
/* allow 1 second to flush*/
void * oldSignalHandler = signal(SIGALRM, mySignalhandler);
alarm(1);
#endif
AllocReq(Close);
GrFlush();
#if GR_CLOSE_FIX
alarm(0);
signal(SIGALRM, oldSignalHandler);
#endif
close(nxSocket);
}
TO THIS:
void
GrClose(void)
{
#if GR_CLOSE_FIX
/* allow 1 second to flush*/
void * oldSignalHandler = signal(SIGALRM, mySignalhandler);
alarm(1);
#endif
AllocReq(Close);
GrFlush();
#if GR_CLOSE_FIX
alarm(0);
signal(SIGALRM, oldSignalHandler);
#endif
close(nxSocket);
nxSocket = -1;
}
