A colleague is getting an error when trying to add a large file with ID UK99.zip I'm sure that the file exists. Adding a test file worked OK. I have tried the same operation on my machine and get no error. On his machine an FTP transfer can upload the file. I run win95 with no network. The error occurs with 2.0.1 Win98 with I think Novell as the network provider. We're just about to go live so I need some input on this. According to my buddy the transaction seems to be doing something, but then after a fairly long time the error happens. Could there be a timeout somewhere along the line?
