Moving Adjustments in the Studio Stack

Studio is working absolutely fine for me in Win 10, as a standalone.
I’m sure in the past I’ve been able to drag adjustments up or down the stack.
I now cannot.
The drag opens the adjustment, but doesn’t move it.
Thanks, and a Happy Christmas to everyone.

Works fine for me in Win 10, just need to click, hold and drag to where you want it to be rather than click. Simply clicking will open the adjustment.

It also happened to me, but it was all right after the next start. So restart Topaz Studio?

It happens to me on occasion as well. I had to exit Studio and restart it, then it was ok.
