DO12 - Icon Confusion in File > New

Icons in "File > New" were swapped by icons on a folder to which I navigated when selecting a status icon for a label. See attachment.

I was unable to reproduce it and I don't know exactly the steps. Previously on the same session I had created new labels and assigned icons to them from a folder full of .icon files.

Could it be a problem with Windows' icon cache?

If it's not reproducible then it probably was a Windows icon cache bug.
