Has anybody else noticed this type of behaviour? I am using a Windows 7 machine running Python version 2.7. It would seem that for these particular MXDs the previous script is held in memory. I have tried reseting the normal mxt file/refreshing the toolbox but no joy.</P><P></P><P>Many thanks in advance.</P></BODY></HTML> Fri, 03 Oct 2014 15:52:47 GMT https://community.esri.com/t5/python-questions/python-toolbox-running-old-version-of-script-when/m-p/159433#M12208 IanRolls 2014-10-03T15:52:47Z Re: Python toolbox running old version of script when working in old MXDs https://community.esri.com/t5/python-questions/python-toolbox-running-old-version-of-script-when/m-p/159434#M12209 <HTML><HEAD></HEAD><BODY><P>Maybe your new script at 10.2 is running updated arcpy not available to earlier versions?
