<div>After kicking off mred -z, did you run the following in your emacs repl:</div> <div>  (current-eventspace (make-eventspace))</div> <div> </div> <div>Does that help?</div> <div> </div> <div>Here's where I first saw that advice:</div> <div>  <a href="http://www.neilvandyke.org/quack/quack.el">http://www.neilvandyke.org/quack/quack.el</a></div> <div>;; Evaluate<br>;;<br>;;   (current-eventspace (make-eventspace))<br>;;<br>;; as the first expression in the stdio REPL, and then it will work the<br>;; way you want.<br>;;<br>;; The GUI REPL creates a new eventspace for evaluating expressions, so<br> ;; the expressions are not evaluated in MrEd's main thread. The stdio<br>;; REPL, however, uses the main thread for evaluating expressions, so that<br>;; it acts just like MzScheme.<br><br><br></div> <div class="gmail_quote">On Sat, May 3, 2008 at 2:07 PM, Andrei Stebakov <<a href="mailto:lispercat@gmail.com">lispercat@gmail.com</a>> wrote:<br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">I am making my first steps with MrEd with gui apps (on MS WinXP)<br>I took a sample of "hello" application from <a href="http://programmingalchemy.blogspot.com/2007/05/open-source-cross-platform-gui.html" target="_blank">http://programmingalchemy.blogspot.com/2007/05/open-source-cross-platform-gui.html</a><br> <br>and pasted that code in hello.scm in Emacs.
