Hey Guys,
Thanks for the feedback! If you can give the developer version a try it may have your fixes for the issue your seeing. The very latest version (0.5.11) can be found by following these instructions:
-> Browse to http://wordpress.org/extend/plugins/duplicator/developers/
-> Look for the section "Other Versions"
-> Click on "Development Version" and download the zip plugin file
-> Uninstall your current version and install this one
Please Let me know if this solves your issue...
Thanks
