I am not exactly sure what version is the author discussing. The post on 20 Mar discusses this version but in fact he is using afferent version of the software. Possibly the same is now called the TS Wavelet, seems the way.
I dont use the program nowadays, anyone who is a regular user can comment on this.
Edit:
I tried the latest version dated 2 Apr and cant find exactly this tab. All the 3 (64 bit, 32 bit normal and 32 bit additional) dont have this particular tab.
