Detect Active application returning 603

Hi Friedrich

When attempting to detect an active application (using the filename) I get a
value of 603 returned whether the application is running or not. I'm
checking about 7 running apps, and most of them return 603, but one returns
accurately (0 for not running and 1 for running). I'm thinking that a
windows release has impacted this, as this is an area of our script we have
not altered for quite some time. Is this something you are aware of, or it
something specific we might be doing?

We're running SetupBuilder 10.0.6124
