Thank you, it works.
So it isn't a bug but a case for "blame the manual".

I've another question. I have an extern functtion coded in C++, compiled with VC++.

Code:
DLLFUNC double CamGetDLLVersion(void)
{
	return 1.43;
}


But when I screen the result of calling the function it differs a litte bit to 1.43. For example 1.41 is the result.
