Yes, Herman, I realized that Tracy's code wouldn't work if Acrobat were already running, as I mentioned in Re: ShellExecute WaitForSingleObject IsRunning(GeorgeTasker) Thread #887963 Message #888036. The issue I was addressing had to do with a flakyness in WaitForSingleObject, even without the complication of a prior instance of Acrobat. For some unknown reason, WaitForSingleObject left Acrobat process residue, but this was circumvented by substituting an essentially equivalent (I thought) piece of code that uses GetExitCodeProcess.
