when I tried to open the “help menu” from the left upper corner of the parameter box, the help message becomes the HTML code instead of the hints of the sop. I do not what I did wrong. Does anyone know how I can change it back to normal help window.

thank you

Yea! Same thing here. Not with all OPs though.
Some work fine, some don't.
I think it's buggie.

Windows 2000 Pro SP4
Quadro4 980 XGL
512 MD DDR
Houdini6.1.325

BTW. Why when I do Help>Version, it says that the version is 6.1.314 :shock: :?:

Installer was 6.1.325

Hmmm! Just uninstalled .325 and installed .331 and it still shows .314 when
I do Help>Version :?
Why is that?

There seems to have been problems bumping up the version number. Despite what it says, the install version number is the correct one.
