"Or you don't actually have to contact the person from if you don't want to, that's OK too."

I have not done yet this because the problem is prevalent and  it seems I have this issue with
a vast majority of products. I assumed that this was a 'Normal' poser bug and that we have to live with..... So that before I complain about the problem to each and everyone that has created these clothes I decided to post on this forum and see if anyone here had experienced the same problems or maybe someone understood these issues and has a solution.

estherau---Thanks for your input... I   I bet there are many others who are having these same issues

lesbently "Have you resaved the clothing at any stage?"
Yes but not all...
Thats a good point... and I have done that on some clothes. But the problems occur also
on  poses  installed directly to the  external runtimes...Could this be a issue? Do they have to installed into the Poser runtime to work? Maybe I will try an experiment to see if thats it.
