Ooopss sorry. I didn't looked into the code I have <*g*>
You right. This is mine:

   Declare Long GetExitCodeProcess in Kernel32 ;
      Long hProcess, Long @nExitCode

   ll_Error = (GetExitCodeProcess(ln_hProcess, @ln_ExitCode) == 0)
   If !ll_Error and (ln_ExitCode != 259)
      *** Do something
   endif

Btw, I have looked into your code. I don't think it will wait if Acrobat is already running. Have you try that ?
