Dear Allin,<br><br>Double-click scripts or session files still doesn&#39;t launch Gretl. Please take a look at the attached files. I&#39;m testing this on a Mac (running OS X 10.8.3) that never had Gretl or X11 installed.<br>

<br>Talking about multiple instance... Today I realized that we have a lot of important softwares that actually use multiple instance (e.g. Terminal, Firefox, and Finder). The way we can have a new instance is selecting &quot;File &gt; New window&quot;. So, if we are going to have this functionality in Gretl, I would suggest to use the same approach.<br>
