[javascript-dev] Re: Re: Strange "undefined" problem using screentoworld...

Okay here is an example...

test.pat...

#P window setfont "Sans Serif" 9.;
#P window linecount 1;
#P message 320 91 39 9109513 random;
#P message 240 91 55 9109513 not_correct;
#P user jsui 240 137 64 64 1 0 0 test.js;
#P message 182 91 37 9109513 correct;
#P connect 3 0 1 0;
#P connect 2 0 1 0;
#P connect 0 0 1 0;
#P window clipboard copycount 4;
