When I open a PowerPoint presentation the pane on the left side of the screed where normally there are two tabs, Outline and Slides and a close button, there is nothing and the view in the pane outline. I have worn out the View Normal button and looked everywhere I can think of and the tabs have not appeared. I am using Office XP on a W2K machine connected to a W2K Server. I have opened the file on other PC’s and everything is fine. Any ideas would be most appreciated.
