Yours could be a Windows issue, but I have something similar happening on my iMac.

For example, if I single-click on an item in my Library to select it, then I single-click on a folder to expand the contents of that, I get a pop-up asking if I want to move the item into a folder - not to the folder I clicked on, but to another one several lines lower down!

This is happening for the first time with Poser Pro 2014. It never happened before, and I don't have issues like this with any other software.
