I seldom have problems with PowerPoint while viewing/modifying presentations. However, when I close the program and move on to other tasks, I sometimes notice the system becomes overburdened a few minutes later. Upon checking the resource monitor, I find that CPU usage is at 100% with PowerPoint using the vast majority. Very strange considering no PowerPoint windows are open.

Is this a known issue? Can anyone suggest a resolution?

Thanks.

if your PowerPoint take up too much cpu, you should consider uninstall your powerpoint version, and install the PowerPoint 2003 or 2007. Good luck!

You can have a PowerPoint process without a window.

One reason is you have preview pane enabled and have selected a PowerPoint File. To preview it an invisible copy of PowerPoint is opened and may not close when you deselect. This doesn't normally use much cpu though.

If you have any addins installed two things (at least) can happen. A badly written addin can have a close procedure that doesn't work. It may keep running when the visible window has closed.

Some AddIns deliberately open an invisible copy of a template as a 'library' if tyhere's a problem this file may stay open.

If you have AddIns try disabling them to see if it helps. If you have preview pane on try turning it off.
