Strange Eraser Tool in SL 10 Pro

I have updated recently from SL 8 Pro to 10 version. But I noticed that Eraser Tool looks strange: it is ellipse now and lost size option. There is all right in 8 version. I attach screens of 8 and 10.

Just change “Spectral Units” back to “Screen Units” :slight_smile:

PS: When in doubt with some tool settings, note that since SpectraLayers 10 you can now display its Online Help page in one click:

I,m embarassed… again.)) Thank you so much!
