0.390731,0.650895  -D1 -U02500,02500 -I-4 -K  flat.dat

It worked just fine on Win2K with only 192MB.  However, I noticed the

(...) Na, don't be quiet... rather, thanks for being obstinate about it! Yes, indeed, you are correct, and it looks like I am all wet. Paint Shop Pro fooled me. My bad. Sorry for any confusion. ++Lar (24 years ago, 1-Apr-03, to lugnet.cad.dev)

(...) I am viewing them at full scale. It's related to the size of the work area, I'm pretty sure, rather than the resolution they're viewed at. 4000x4000 is a pretty good sized chunk of memory, I expect. Gyug sent me a note, he's looking into it. (24 years ago, 31-Mar-03, to lugnet.cad.dat.models)
