Oh I thought I was the only one with that problem. Only mine is in PP2014. I think it's a "user error" - or rather a mouse error, but I agree, it's highly irritating. It's like a mouse delay or something. So that when you click a folder, Poser sees it as a dragging. I don't know if it would help to change the overall mouse sensitivity?

Anyone else with this prob?

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
