This article contains the answers to frequently asked questions (FAQ) about PowerBook software.

• Q: I want to use the Control Strip software on my desktop Macintosh. Is this possible?
• A: Apple supports use of the Control Strip software only on PowerBooks. There are third-party patches to allow use of the Control Strip on a desktop Macintosh, but this solution is not supported by Apple.
• Q: I am trying to use PowerBook File Assistant to synchronize two files but I get the error message that they do not have the same creation date. How can I get around this?
• A: PowerBook File Assistant will not synchronize two files that have the same name but different creation dates. There is no workaround.

  If File Assistant generates this message in error, remove the Assistant Data file from the Preferences folder within the System Folder, and set up the synchronization again.

• Q: I have connected a 14-in. display to my PowerBook 180, but I am only getting a 640 x 400 image on the external monitor. What should I do?
• A: It sounds as though you have video mirroring enabled. Open the PowerBook Display control panel and see if mirroring is on. If so, it generates the same image on both displays. Since the PowerBook 180 screen resolution is 640 x 400, the external monitor mirrors that resolution.

  Turn off mirroring, then check your settings in the Monitors control panel. To make your external monitor your main monitor, drag the menu bar in the Monitors control panel from monitor 1 to monitor 2.
