Remember that's 360 plus or minus about 240 on Netscape, depending on mood and time of day. I hope you incorporated a nice safety buffer
open ('Whatever", "Whatever", "width=360,height=400");
Is there something wrong with that code or does Netscape just not like window sizes being specified?
By the way, the 360 is perfect on my box too (which happens to be 1024x768 as well, so no surprises there).
