When using ChirpZ transform of LabVIEW(The example itself provides) to refining the spectrum, I found a strange thing. When the frequency is very big and the range is small together with a not small number of ChirpZ transform, Error happened(very bad spectrum and wrong frequency ChirpZ's result is)! Nothing is wrong with the examples(I've scripted other VIs to verify this), and this error didn't happend using MATLAB. So I believe that is a bug of LabVIEW!!!(Not Sure yet of course). I Need Help! Is there any error? Or is there a bug of LabVIEW's ChirpZ tansform? I've already uploaded the codes and screenshot.May you have a look.

Crosspost from here, didn't get momentum there though. I'm trying to prevent accidental stealing of focus from a string control by discarding the Mouse down? filter event. It turns out however that mouse down on any control or indicator that can take any input, such as strings, numerics, paths etc takes focus away from the string control. Is there a use case for this that I can't see or is it a bug? FocusLab.vi
