I haven't looked at your example yet. The intent is that when the paint
handler is called the isigraph with the event is automatically set as
the target for gl commands in the paint handler. The only time you need
glsel is for code not under a paint handler or when you want to gl stuff
to a control other than the one the handler was called for. Do you
observe otherwise?
Ah, just read your message more carefully and see the magic word
capture. This is a capture problem, not a glsel problem. Until capture
is released all mouse events go to the isigraph that did the capture (no
matter where the mouse is). My guess/hope is that this is a bug in the
grid J code that is just not doing the capture release in some case.
We'll try to reproduce the problem and see what if going on.

Subject: [Jbeta] Grid fails on "default gl control" issue
To reproduce
* run the script below
* click inside second grid
* drag the thumb of scrollbar on first grid
As a result, the first grid is locked
together with any other J windows and controls,
except the second grid. Capture was invoked
on behalf of the other grid, because on the
mouse down event, there wasn't a "glsel" for it.
There is a simple solution to simplify and
foolproof all gl2 code: to issue glsel on
any isigraph event, implicitly inside WD.
The only exception is when you control painting
of one isigraph from external events.
That's the only case when explicit glsel
will be needed.
The "default gl control" issue is described at
