Circles appear squashed a bit in 2D dreawings

It just happened when i started a session, and i can't get circles to appear round again...is this a bug? Even when i plot preview it's the same. Autocad 2004.

Squashed or appearing as polygons? If polygons try changing the VIEWRES setting to something higher like 2000.

not truncated...or polygonal, elliptical. as if viewed at an angle. but it is right off the bat at the start of the session. looks stretched, kinda. wasn't panning global or anything like that. strictly 2D x-y.

Did you change your display resolution? Did Windows update change it for you while you weren't looking?

Sounds like an adjustment to the horizontal display is required via the OSD.
