Right-click on the My Computer icon on the Windows desktop,
left-click on Disconnect Network Drive, and disconnect any mapped
drives that are not currently available.

I've opened a document and am trying to insert a picture from file.

When I try and navigate to the location where the picture is stored the open
picture dialogue takes upto 3 minutes to respond to a change of folder,e.g.

E.g if it defaults to My Documents and I then double click on say folder
Nick it would take 2 mins to open the Nick folder.

Any ideas please?
