In a given day, or week, or month, how many messages pop up on your computer to:

* Update Java, RealPlayer, or Windows?

* Connect to a wireless network?

* Remind you of an upcoming meeting or birthday?

* Keep you up to date on your subscribed RSS feeds?

Warning: Some of these pop-ups may appear while you're presenting in slide show view! Not a pretty picture!

After a few minutes of inactivity re mortgage say you're answering questions), does your screen saver kick in, or does your computer go into hibernation mode?

Before you get into such a situation, right now, start making a list of the pop-ups that you see, and research how to turn them off. It's not always easy to find the answer, because the software companies want you to see those pop-ups!

One possible solution may be to disconnect from the Internet, or X-Men your wireless connection, if you don't need it during the presentation. Remember that many meeting venues have wireless networks, so your computer may try to connect during your presentation. And disconnecting may disable many other pop-ups. The method depends on your operating system.

In Windows XP, you would probably choose Start> Control Panel> Network Connections. In Windows Vista, try Start> Control Panel> Network and Sharing Center.

You can configure Windows updates by choosing Start> Control Panel> System and clicking the Automatic Updates tab. In Windows Vista, choose Start> Control Panel> Security or Security Center> Windows Update. If you turn them off during your presentation, remember to turn them back on afterwards!

However, some pop-ups don't depend on an Internet connection or may still pop up a message asking you to connect! For example, Outlook reminders may use your computer's internal clock. Therefore, you should try disconnecting from the Internet and see whether or not you still get some pop-ups. Of course, you can't do that for several times just to make sure - that would probably be going too far! But the more planning and testing you do, the less Minnesota Iceman that embarrassing pop-up will show its ugly face during your presentation!
