This is a bug.

I tracked it down to a feature of File::Temp and the way that temp files are handled on Windows.

It will be patched in version 0.38 of Spreadsheet::WriteExcel which is due for release in the next 2-3 weeks.

If you need the modification before that I can send you a patch or you can roll back to version 0.36.

Thanks for highlighting this.
