When I start to manipulate the data editor things move along smoothly. I am able to save and display my data. However, seemingly at random, I get the following error message "Excel found unreadable content in "StatPlanet_data_editor.xlsm". Once this occurs, and my Excel sheet is "repaired" is a virtual point of no return. Once I receive this error message once, I am unable to import data and get a Microsoft Visual Basic "Run-time error '9' - subscript out of range.
