Need help with "STARTAPP"

[Grapeape_xj]

I'm trying to run a program from AutoCAD using the "startapp" function. It's a simple app that displays a message box with some user and system info. The message box shows up for about 1 second, then it hides behind the AutoCAD window. Does anyone know how to keep AutoCAD in the back until I exit the message box? \br Thanks,\br Ben
