Q&A

Can I configure Host Presenter so that my e-mail host is already set?

Yes you can. Open Host Presenter and select the Setup menu. In the Host: section type in your e-mail host name, e.g., pobox.upenn.edu. You shouldn't have to alter the General Unix Profile in the Session Name: section. After you set your e-mail host, select the Profile menu and then select Save as Default Profile. Your e-mail host is now set as the default. For additional information regarding Host Presenter, check the tipsheet at http://www.upenn.edu/isc_comm/internet_tipsheets/windows/host.html.

I've copied a Macintosh alias file from a diskette to my hard drive. Now each time I double-click on the alias, the Macintosh prompts me to insert a diskette. Do I have to put the disk in each time?

A Macintosh alias file is a pointer to an original file, not a copy of that file. It sounds like the alias you copied points to a file located on a diskette. In order for the Macintosh to provide the file, you will need to insert that diskette. If you will be using the file often, copy the original file to your hard drive, then make a new alias of the file and delete the old alias.

Can forged or threatening e-mail or news postings be traced?

Usually such messages can be traced. Don't delete the message. Make as complete a copy of it as possible, including all of the headers, which help in tracing. Most e-mail and news readers only display limited headers unless you specify otherwise. To view detailed headers in Elm, select the message, and type h. To view the headers in Eudora, select Switches from the Special menu, click the Show all headers box, and then view the message. If you don't know how to display all of the headers of a news or e-mail message, consult your system documentation, or check with your computer support representative. Once you have a complete copy of the message, contact the Univer sity Information Security Officer (security@isc.upenn.edu).

Is there a way to copy a number of files at once from my Macintosh to diskette for backup?

If you are using System 7.5 or higher there is. Use the Find command from the Finder's File menu to locate the files you want to copy. Then select the files from the Find window and copy them to their new location. If the diskette to which you are copying has insufficient space for the files, you will get a warning message.

Recently I have had to reset the date and time in the General Control Panel every time I start up my Macintosh LC. The date and time seem fine while the Mac is on. What's the problem?

It sounds like the battery that keeps the date and time current when the Macintosh is off is dead. You can replace it yourself (replacement batteries are sold by Apple Macintosh dealers), or have a dealer replace it if you don't feel comfortable opening your computer.

Recently I tried to open a file in Microsoft Word for the Macintosh. The file refused to open and the dialog box said "The document could not be opened, because the application program that created it could not be found." But I do have the application. What's the problem?

Your desktop file, the file that keeps track of documents and the application programs that created them (among other things), has probably been corrupted or damaged. If so, your file will appear with a generic icon instead of a Word icon.

You can usually repair the damage by rebuilding the desktop file; this recreates the link between your Word document and the Word application. To rebuild the desktop file, restart your Macintosh while holding down the Command and Option keys. Keep these keys held down until the dialog box appears that asks "Are you sure you want to rebuild the desktop file on the disk? Comments in info windows will be lost." Click the OK button to confirm that you want to rebuild the desktop file. Your file should now appear with a Word document icon and should open.
