onhilite is used on controls that represent buttons (in the usual 
computer GUI sense) and is triggered whenever the button should 
highlight or unhighlight: Highlight when the mouse goes down on the 
button, unhighlight when the mouse, still down, leaves it, highlight 
again, when the mouse, still down, reenters it, unhighlight when the 
mouse goes up, etc. You should find many examples of this in the 
internal nodes (main menu, Lua command line, etc.) that are stored in 
the "Pipmak Resources" ZIP file (on Windows and Linux); the demo project 
has one on the title node too.

onenddrag is triggered when the mouse goes up after it went down on the 
control, no matter where it is now (onmouseup is only triggered when the 
mouse goes up on the control). Search for "onenddrag" in the demo 
project, I think it's used there a few times too.

Incidentally, these two events are the ones that were not directly 
modeled after HyperCard (except for the spelling of "hilite"). onhilite 
is necessary because HyperCard handles the highlighting of a button 
internally. onenddrag is an addition that seemed useful to me - in 
HyperCard, such things were usually done in ways like "repeat while the 
mouse is down", which doesn't work in Pipmak.

I guess I should complete the documentation about these one day...

Not at all - that sounds like a pretty serious bug. One that I've never 
heard of. Do you think you'd be able to figure out what's going on yourself?
