4wd, is that cool, or what. You always seem to come up with good solutions. My man!
Here's another little approach I discovered....
WScript.Timeout = 3
x=msgbox("Screenshot Capture Successful!",0,"Great news....")

Place full path and filename into mouser's "Invoke..." box. Apply. Save.
Presto.Show brief message on screen
