The option you are looking for is "-size=1024x768" or whatever suits you. See also the file "pcc2help.html" in its program directory or in the start menu folder.
Precisely.
It still looks ugly because it doesn't really adapt the screen layouts. I know that and I'm working on making it better, so you don't have to file bug reports that it looks ugly at 1024x768 :-)
