It happened however this week that i had to<br>give a talk in which i wanted to reuse some of the drawing i had made<br>using xy in the papers. It worked fine, with a major exception: <br>the head of all the arrows is tiny, and almost invisible on the<br>screen. So people in the audience could see the lines of the arrows<br>i had, but could not see which direction the arrow was going (i am<br>using simple arrows of the form ->). <br>Can somebody tell me how to make the head larger? <br>I need it urgently, as i have to give a talk tomorrow.<br>Thanks,<br>Bruno<br></div></div></div></div><br><br></div></div></div></body></html>
