Bill, the DropsP5.pyd and DropsP4PP.pyd are in the same folder with the Drops.py file so I don't understand why the script can't find them. All three files are in both the C:appsposer4RuntimePythonposerScriptsWeirdJuice folder and the C:appsposer5RuntimePythonposerScriptsWeirdJuice folder

I just tried running the script in PP this time and got this error:

Traceback (innermost last):
File "", line 24, in ?
ImportError: No module named DropsP4PP

I'm opening the drops script located in the Poser 4 Pro Pack Runtime, not the P5 folder. I deleted the unnecessary DropsP5.pyd file in the Poser 4 PP Runtime folder as you suggested and tried again after reinitializing Python. I got the same error about no module named DropsP4PP found.
