FFT in CVI

Hello CVI user,
I use the FFT function in CVI, sometimes
the FFT calculates every second "Q" value as "not a Number" (NaN)
e.g. I can verify this behaviour if I feed the FFT with constant zeros for
I and Q.
Normally the result should also be also zero's.
The problem occurs not every FFT call and the FFT returns no Error
(both Arrays are defined as double- N = 1024)

Could this be an NT problem? With W98 it seems to work

Thanks
Klaus
