I have an Excel 2010 spreadsheet with VBA code. When I try using it in Excel 2013 some strange stuff happens:
The Command Buttons on the existing worksheets stopped working. The VBA code associated to them does not run. Not even an error message appears.
I tried adding a new Command Button to an existing worksheet, but it does not run either.
But, if I create a new worksheet in the spreadsheet, and add a Command Button in it, the button executes with no problems.
