hrv/scl values sometimes (regulary in a loop) not correct

[Erik01]

I compiled the liblightstone1.5 to a dll-file and also the liblighstone-test.exe.
Then i tested the exe and i programmed also in labview an access to the functions in the dll.
But in both cases there are sometimes (in regular distances when the function lightstone_get_info is called in a loop) cases where the scl or/and the hrv values are zero (0.000) or one of them is zero and the other value is extremly high (around 62).
lightstone-test.exe generates 10 value-pairs and if you run it more times you can see these error-value-pairs also.
I took the win32-library when i compiled liblightstone.

What version of windows is this on?

I tested it on Win XP and Win7 Home 64 bit. On both systems were the same results.

New Info: I bought an IOM also. Here these error-value-pairs appeared very rare (but they appeared) on both computers (notebook with Win7 Home 64bit, Desktop with Win XP 32bit). On the lightstone (Turtle) these value-pairs appeared very often (regulary) on both systems.
