[Zope] Zope + Web Folder

Hi, I have Zope installed on Win98 and tried to access different object from a Web Folder. I have no problem to log in. I also can see the different folders and documents. But there is no way to copy any document from/to my Zope site to/from my local machine. I have a message like "Error while trying to copy one or some of the selected files" (the actual message is in French). However, I'm able to delete the files on Zope site using the same Web Folder. I tried to do the same with another site not powered by Zope and it works perfectly fine. Any idea, pointers? Thanks. ****************************************************** Oscar Picasso picasso@videotron.ca ******************************************************
