Notable Changes in Igor Pro 7.07



  • Dramatically increased the speed of loading Excel .xlsx files containing very large numbers of strings.


  • Addressed incorrect handling of comma and semicolon when double-clicking just before the comma in "123,456,789" and "123;456;789;" or when option-right-arrowing or option-left-arrowing in such text.
  • Windows: Fixed Window Tiling/Stacking Area dialog when Igor's MDI frame window is positioned on a secondary display.
  • Fixed setting of the "from cell" and "to cell" vallues in the XLLoadWave dialog when changing the selected worksheet.
  • Fixed Find Text in Multiple Windows dialog to allow searching for case variations of the same word (eg. "wave" and "WAVE").
  • Fixed initialization of Y axis coordinate system control in Draw dialog.
  • Windows: In Igor Pro 7.00 through 7.06, if an ActiveX client launched an Igor instance, a crash would occur if the client called an Igor method before Igor finished initializing. Now the client call to CreateObject (Basic) or CoCreateInstance (C++) will not return until Igor has finished initializing.
  • Windows: The errorMsg output from the ActiveX Server Execute2 method was broken in Igor Pro 7.00 through 7.06. It now works.
  • Windows: The history output from the ActiveX Server Execute2 method was broken in Igor Pro 7.00 through 7.06. It now works.
  • Fixed an infinite loop in the Notebook Action dialog if you clicked the Generate LoadFile Command and then chose a file outside of the Igor Pro folder.
  • Fixed handling NaN values when using ImageThreshold with a threshold wave.
  • Changed increments on the profile width spin-box in Image Line Profile dialog.
