It's either Windows 10's fault, or PP11's fault, but let's just put it down to the Poser Library not being able to show me a + button to add my created content to the Poser Downloads Library. It shows an Add New Folder button, but when I click that, nothing happens. So I get back into Windows Explorer and uncheck the Write Only Permissions for all the folders in Downloads Runtime. Drill down to check ! And I created a new folder under the Materials folder of the Poser Downloads runtime, using Windows Explorer. I re-launch Poser Pro 11, and now I can see the new folder I created, and I can see the + buttons, which allows me to add content to whichever sub-folder I am in, under the Downloads runtime.

I also mentioned this solution briefly at the end of a thread I had started over at the Official Poser Forums ( at runtimedna website). I thought it may be useful for others who experience the same issue.

I personally stay away from Poser's core runtime and download runtime. I am better off using all external libraries to save and access content. Too much of an issue dealing with Windows UAC.

@hborre - hmm, yes, I should have thought about that sooner.

I find that I can only add one external runtime at a time - then the library stops responding and I have to restart P11 to get it added. This is on a 64-bit Mac. IMHO, the Library system in Poser (not new with P11) needs to be completely reworked. Not automatically or even easily alphabetized, etc etc ...

Do you have the latest SR's installed?
