I did not assume anything, your post was not very clear about your 'testing' methods; and that led me to the conclusion that your test was flawed. Further in your rebuttal you did not indicate wether even on that one machine if you attempted any installs without use of GHOST or similar application, or if you tried different install order of the suspect and affected application.
Next week when I don't need to have my machine fully functional for training purposes, I will test this SKYPE issue using my own methods.
I have seen no such issue being widely raised by C3D users about SKYPE and point group edits causing any problems.
Again it could be an order of install issue, in that one should most likely install this SKYPE crap prior to installing C3D and then there might not be an issue at all. Did you test that particular install order? Skype first, then the C3D install?
And or did their IT person (whatever their qualifications are) also install SKYPE first and then C3D without use of Ghost or similar?
Or do you even know what actual steps were taken; being X miles away makes me think not.
Until I do further testing on my own I will leave you to decide if you want to test the install order as a cause/solution to this.
Maybe others are open to an alternate solution whereas you may not, so my suggestion to test the install order might help them.
Interesting to note that a google of " skype point editor " only returns your post here; so this must be one massive problem for sure.
Other variations return no results of any note regarding C3D at all.
