I don't see anything manifestly wrong. I wrote a simple test
program putting your principles to work. The program, named TEST,
works perfectly. I include it below.
You don't mention what version of IDL you are running,
but mine runs fine in IDL 5.2 on Windows NT.
Cheers,
David

Ken,
I can not see any difference in how you defined 'display_1' and 'display_2'
in your sample code - they are totally identical. If you are saying that one
does pass events and another does not, there must be a difference in your
real code - possibly a typo which causes xmanager to direct events from
'display_2' to a wrong destination.
I have no idea what did you use /JUST_REGISTER for. I never used it and all
my applications (quite complex multi-panel, multi-layered, multi-window, with
obj graphics and read/write, etc.) work ok. Try getting rid of this keywords.
Try at the very end of laying out the widget trees doing:
widget_control, display_2_id, event_pro = 'manifold_event'
If it helps, then you have a typo in the code above it.
Cheers,
Pavel
