I have a function that renders a Direct3D scene.If I call this function
periodically through a timer everything works ok.But if I put the same
function in a thread the application stops responding, or responds with
a lot of delay, to its own messages(mouse clicks, movement).The thread
has TP_NORMAL priority, and the function is called using the Synchronize
method.

Here's some sample code:
In the thread:

void __fastcall TRenderThread::Execute()
{
 while(!Terminated)
 {
  Synchronize(f);
 };
};

where f  is:

void __fastcall TRenderThread::f(void)
{
 Render();
};

And, using a timer:

void __fastcall TMainForm::TimerTimer(TObject *Sender)
{
 Render();
}

Render is the function that renders the Direct3D scene.

Bogdan.
