Hi Everyone, OK, ifeffit-1.2.5a.exe is available on sourceforge and the main Ifeffit page. This seems to fix the plotting problem -- it worked on the 5 WinXP machines I tried. An 'update' was also posted (we're now at update #5) that will fix the problem (in the next day or so, depending on when you last ran athena or other Ifeffit applications). If you've installed ifeffit-1.2.5.exe and can't wait that long, you can apply the update by hand by downloading http://cars9.uchicago.edu/ifeffit/updates/ifup_005.zip and unzipping this (following the directory structure!) in the main Ifeffit directory (C:\Program Files\Ifeffit or C:\Ifeffit). If you haven't installed the broken ifeffit-1.2.5, please don't use this shortcut, as this update is not a complete update from 1.2.4!! Sorry for the problem, and thanks to Doug, Scott, and Michel for the reports! --Matt
