Problem with pdf file UPLOAD
I have a strange problem: Each time I try to upload a pdf-file into on of my new made instructables, it just happens nothing.
I can upload pictures with the new and the old uploader, but when I try to upload a pdf-file, the file upload-dialog closes and nothing appears in the library or on the recent upload list. Sometimes instead of the pdf, the last uploaded picture appears on the list.
I already tried deleting all the cookies and restarting the system, no success.
Currently I'm working with WinXP and firefox, but I also tried from another computer with Opera and IE.
I guess it's some kind of bug in the uploader, or not?
