Recently I have seen this problem manifest itself at two customers, so I thought I would post about it to save anyone else running into it, or scratching their heads. When you customise project workspaces, or SharePoint workspaces in general, you have two options to remove the web parts from the page: Close the web part – this stops the web part being rendered on the page, but still being created on each page load Delete the web part – this removes the web part from the page completely.
