Have the toolbars in Microsoft Word, Excel and/or PowerPoint 2008 disappeared on your Mac?
If they have an you haven't figured out how to turn them back on or you turn them on and the next time you open the application you are back at square one (no toolbars), you can actually thank Apple and not Microsoft for this "feature".
The next time you open one of the Office 2008 applications, take a look and find the oblong button at the right end of the application's title bar. Click it - your toolbars will switch state - from hidden to visible or vice-versa. Why you would want them hidden is something I will never understand.
If your toolbars haven't disappeared on you yet, just knowing how this "feature" works just might lessen the pain should an errant click occur.
