I have identified a problem with the way Netscape 2.0b3 for Windows uploads files. I am working on a workaround. In the meantime after you have used Browse... to select the file to be uploaded, please manually delete the pathname component of the filename. That is, if Browse puts the pathname C:\fff\mynfo.fff in the filename box change it to mynfo.fff.
Unix Netscapedoes not appear to have this problem.
