thank you for your response.
I experience a difference between the Trackpoint and the mouse wheel:
the mouse wheel always works fine.
Even an xterm that lived for quite a while and that shows this deferred scrolling
on using the trackpoint, I can without problem scroll using the wheel or using xterm's scrollbar.
I think we agree, that the trackpoint events ARE generated (because otherwise there would not
be deferred scrolling but no scrolling).
So the question is, where these events get buffered.
If xterm treats wheel and trackpoint the same, the trackpoint events get buffered in a component
between XWin and xterm?
In case you want me to run a beta test, also for the blind key (dead key) issue,
pls let me know.
