Well, typo, after all! Told ya!
GROUP_LEADER : the only use I have for it is to kill a dependent top-level base,
like a modal dialog.
JUST_REG : I have never used it and from the description I see no use for it in
what I am doing.
EVENT_PRO: This is just redirector for the event handling procedure, to let you
bypass the default "your_pro_EVENT" procedure name. XMANAGER still provides event
handling (unless you are advanced enough to use WIDGET_EVENTdirectly, which I
never needed).

In my first useful widget application (not big, <1500 lines of code) I used one
event handling procedure. As I expanded it, it quickly grew out of reasonable
limits, it became difficult to find and change things. Now I have separate event
handling routines for logically related tasks (modes of application operation:
data loading, application setup, integration, time series analyses, etc.). This
way event handling parts don't screw up each other and it is easy to expand one
of them without going through a lot of code.
Cheers,
Pavel
