Hi Tim,

>I have an application (written in VFP6) that I need to keep secure and have only ONE instance of it running on any given workstation.

Since you are using CodeMine, why not let CodeMine do this for you. Make sure the CodeMine AppMain.Application.lSingleInstance = .T., then CodeMine only allows once instance of an application to run on each machine.
