In the installation directory (c:\program files\TwoToneDetect) there should be a "data" folder. In that folder there should be a file called "config.cfg". If that file is not there, create a blank file with that name and extension (using notepad, for example). That should solve the problem. I may have accidentally put out a version that didn't include that file.Everytime I shut down your program I get an error box that comes
Error 8 occurred at Open/Create/Replace File in Write Spreadsheet String.vi->Write To Spreadsheet File (string).vi->TwoToneDetect10.vi
and any changes I have made to the program are lost when starting the program again.
