Last Update 12/16/2002 This ActiveX dll can be used to create a Mutex.  The purpose of this mutex may be to prevent additional copies of a script from being executed on the same system at the same time.  A Windows Scripting Host program (testmutex.wsf) is included that demonstrates it's use in Object Rexx, VBScript, and JScript.  The code in the VBScript section can be cut and pasted to a .vbs file if desired. This ActiveX dll was created in VB6 and requires the VB6 runtime files.  Don't forget to register this dll with regsvr32.exe.
