I have an app that reads and writes data to zip files. When opening one, I use a JFileChooser with a file filter for zips and directories. This works fine except except on XP. If the zip file is on a remote (Novell) file server, the JFileChooser treats the zip file as a directory. You can't open the zip file itself. If the client is W2k, there is no problem. I'm using JRE 1.4.1. Anyone know if there's a tweak to XP to fix this?
