Hello,
i get this Exception:
An unhandled exception of type 'System.Runtime.InteropServices.ExternalException' occurred in System.Drawing.dll
Additional information: A generic error occurred in GDI+.
as soon as i call the method:
```
xlsSheet.Cells[1, 1, xlsSheet.Dimension.End.Row, xlsSheet.Dimension.End.Column].AutoFitColumns()
```
on a Sheet with 1158 rows and 18 columns on v4.0.5. This has worked in v4.0.4.
