Object turn grey when erasing

[Anonymous]

When I am doing an erase and I do a selection window the objects I have selected turn grey.  This also occurs when I do a fillet, the lines that will no longer be existing turn grey.  Is there a way to turn off this feature.  I do not like it and I don't recall it being like that in the past.  Seems to have started in the last couple of days.  Running AutoCAD 2018.

Hello @Anonymous,

Try changing the option below:

Options  ->  Selection Tab  ->  Preview

Uncheck the "Command Preview" option.

Thanks!
Due to background glare, I could barely see the objects to erase once I selected them.
The potential for erasing the wrong thing was very strong...
