Paul,
Here is the briefest demonstrator I can create:
WINAPP
OPTIONS (INTL, DREAL)
PROGRAM HELL_P
C --------------
INCLUDE <WINDOWS.INS>
A = 1.0
IW = WINIO@ ('%ca[Illustration of help]&')
IW = WINIO@ ('%bh&', 1)
IW = WINIO@ (' Parameter A %?rf[initially_blank]'//
& '[Put a value for A here]&', A)
IW = WINIO@ ('%2nl%rj%8bt[Accept]')
END
The pop-up help has a black rectangle background instead of being transparent, and so looks awful.
As it happens, a workaround (improvement?) is to use %th with the balloon option instead of %bh.
Only Win32 tested.

PS: When I was younger, so much younger than today, I never needed popup help in any way .... etc
