FileExplorer comma character in Chrome

[Kjell]

Problem to using the comma in the file name in Google Chrome. I have "ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION"
How can I solve it?
No problem using the comma in Explorer, Firefox or Safari......

I solved the problem by changing the Handler.ashx

Change:
response.AddHeader("content-disposition", "attachment; filename=" + fileName);
to:
response.AddHeader("Content-Disposition", "attachment;filename=" + '"' + fileName + '"');
