Hi Sture,

Thanks for reply. In this case, there is no file in the target end with this same name. We tested this with various files, and, seems like the framework or browser understands the name part after the first "." in the file name as the extension of the file and aborts the operation, like a not allowed file type. The OnFileUpload never fires. I can't find a way to debug this because any event fires after the file selection.

I don't know if I could explain exactly the problem with my poor English...
