Hi Doug, This may be a brand new bug in the Ifeffit 1.2.5 download. I am also using XP, and it was working fine under 1.2.4. I downloaded 1.2.5, and when I try to import any data (even the example files that come with the package) into either Artemis or Athena, they crash when they try to display on the graphics screen. To be specific, I can see the data get read in, but when it gets to the stage of graphing the data, the main Artemis or Athena screen vanishes, the program icons go away from the task bar, and the graphics screen remains, but it is blank. I had not yet determined for sure that this was the fault of the new version...I was going to try some things like redownloading it, and checking to see if 1.2.4 still runs, but if you're seeing this too it may be a problem. --Scott Calvin Sarah Lawrence College
