Load the icons into Tools/IconEdit. If it's a newicon,
then it will tell you it will remove the newicon info.
OK the requester & re-save the icon.
You can also open Prefs/WorkBench & play with the icon
settings on the right like "no newicons" & the quality
settings. If I check on "no newicons" then some of my
icons turn to dots. Make sure it's off.
I had to replace some older icons with 256 color glow
icons when going from 3.1 to 3.9.
