Document.Reload (Word)

Reloads a cached document by resolving the hyperlink to the document and downloading it.

This method reloads the document asynchronously; that is, statements following the Reload method in your procedure may execute before the document is actually reloaded. Because of this, you may get unexpected results from using this method in your macros.
