in thread System Function...script does not move until process ends.

dbspawn is a much better solution than the hack I wrote about. Please disregard my "cmd /c start dbeng9" suggestion.

I usually avoid the command because it is not the appropriate tool for launching the db engine as a daemon (use dbeng9 -ud instead)...however it is designed for exactly the type of situation you are facing.
