[Zope] importing

I try to import a file.zexp which is an exported folder. The browser doesn't stop trying to import, but nothing happens. The file is about 2mb of size. After about 10 minutes I stop the import. No traceback or error message. What is going on here? _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
