Multithreading under NT

Hi,

this is my problem:

unsigned long __stdcall Thread(void *)
{
 Cda_Def cda;
 long value = 1;
 memset(&cda, 0, sizeof(cda));
 EnterCriticalSection(&cSection);
 oopen(&cda, &lda, 0, -1, -1, 0, -1);
 oclose(&cda);

 LeaveCriticalSection(&cSection);
 Sleep(1000);
 EnterCriticalSection(&cSection);
 LeaveCriticalSection(&cSection);
 return 0;
}

this thread hangs if it is spawned twice. The second thread hangs in oopen wich causes the first thread to wait infinitly entering the critical section after the sleeps.

[Quoted] [Quoted] There are three possiblities to make it work: 1. omit the oclose
2. force a thread switch before the oclose (put it into the second critical section)
[Quoted] 3. omit the opinit(OCI_EV_TSF) at startup.

It seems that oopen waits infinitly calling WaitForSingleObject, but i'm not shure.

Any suggestions ?
