 * Microsoft Word for Windows 95, versions 7.0, 7.0a

SYMPTOMS
If you have one instance of Word running and you start Word again, you have two instances of Word running instead of one as expected.

CAUSE
In Microsoft Windows, if a share program such as SHARE.EXE, VSHARE.386, or any other share utility is in use, multiple instances of the same program can be run at the same time. You cannot configure Word to prevent this from occurring.

"http://support.microsoft.com/directory/overview.asp" The following WordBasic macro, when named AUTOEXEC, will check to see if any other instances of Word are running and if so, give you the option of closing one instance or allowing the new instance.

  Sub MAIN On Error Goto bye Dim ListBox1$(1) size = AppCount - 1 Dim winnames$(size) iCount = 0 Text$ = "There is currently another instance of Word " Text$ = Text$ + "for Windows running. Please choose " Text$ = Text$ + "the instance you wish to Close or " Text$ = Text$ + "choose Cancel to run both instances." AppGetNames winnames$ For i = 0 To size If InStr(1, winnames$(i), "Microsoft Word") Then iCount = iCount + 1 ListBox1$(iCount - 1) = winnames$(i) End If        If iCount > 1 Then Begin Dialog UserDialog 322, 174, "Microsoft Word" OKButton 222, 121, 88, 21 CancelButton 222, 147, 88, 21 ListBox 10, 70, 300, 45, ListBox1$, .ListBox1 Text 10, 6, 300, 60, text$, .Text1 End Dialog Dim dlg As UserDialog If Dialog(dlg) = - 1 Then AppClose(ListBox1$(dlg.ListBox1)) End If           i = size End If     Next bye:'<-- This line MUST be left aligned End Sub To test the macro, restart Word and then start a second instance of Word. You should receive a dialog box stating there are two instances of Word for Windows running. It will allow you to:


 * Choose one instance to close.
 * Choose Cancel to allow both applications to run simultaneously.
