Hi Jeff,

I have created a small SetupBuilder 2019 project to start (from within a
Loop/End) a "dummy" JUNK.EXE Clarion executables 250 times. After that, I
started one instance of JUNK2.EXE and fired a "Detect Active Application"

It returned 603. That means, JUNK2.EXE is not active. But this is WRONG
because JUNK2.EXE is definitely running!

Then I compiled the very same project with the internal version of
SetupBuilder 2023.

This time it returned 1.

So it seems to me I already fixed this. Checked my source code history and
see that I already worked with Capesoft on a similar issue. So it seems to
be related.

If you are interested, I can send you a small compiler library to check it

Thank you for bringing this to my attention.
