I have the following property set: 

uploader.FileTooLargeMsg = "{0} cannot be uploaded!\n\nFile size ({1}) is too large. The maximum file size allowed is set to: {2}."

But when the javascript alert is displayed the escape characters (line breaks; \n" are displayed) rather than being interpreted as line breaks.

Also tried using double slashes - no luck ...

Also tried using <br> instead of \n\n - no luck

Any ideas?
