      <title>Copying text from the AI panel</title>
      <link>http://www.mapleprimes.com/questions/243573-Copying-Text-From-The-AI-Panel?ref=Feed:MaplePrimes:Tagged With Maple</link>
      <itunes:summary>&lt;p&gt;I do not understand why a once entered prompt cannot be copied from the AI pannel.&lt;/p&gt;

&lt;p&gt;I also do not understand that a text passage from an answer (e.g. a proposed help topic) cannot be selected and copied to the clipboard with crtl-c.&lt;/p&gt;

&lt;p&gt;It does not make sense to me to unnecessarily&amp;nbsp;restrict a new program feature. This somehow spoils the show.&lt;/p&gt;

&lt;p&gt;Is that a restriction to Windows or my local setting or something imposed on Maplesoft from a third party supplier?&lt;/p&gt;

&lt;p&gt;Has anybody seen similar AI implementations in other products?&lt;/p&gt;

      <link>http://www.mapleprimes.com/questions/243569-AI-Code-Diff-With-Respect-To-A-Function-Call?ref=Feed:MaplePrimes:Tagged With Maple</link>
      <itunes:summary>&lt;p&gt;Hello Ladies and Gents :)&lt;/p&gt;

&lt;p&gt;I asked Maple AI to write a program to calculate the geodesics on a sphere.&lt;/p&gt;

&lt;p&gt;see the attached ws.&lt;/p&gt;

&lt;p&gt;When running this program I receive an error which I don&amp;#39;t understand.&lt;/p&gt;

&lt;p&gt;of course i know how to do it by paper and pen, it was just a test.&lt;/p&gt;

&lt;p&gt;if someone could explain me this error i would greatly appreciate .&lt;/p&gt;

&lt;p&gt;thank you and kind regards,&lt;/p&gt;
