[Cuis-dev] Trackpad issue

[Gastón Caruso]

Hi all, I'm facing a bug that is driving me crazy haha.

Sometimes, when I scroll down on a SmalltalkEditor the scroll right / left
of my mac trackpad is recognized as a keyboard event including all of the
modifier keys, which means that it will select all the first line of what's
in the editor. This is, if you're looking a long method, you'll be taken to
the first line.

This is really annoying and it's happening on Pharo too as far as I can
tell.

To get more information of what's happening I added a print on
EventSensor>>#fetchMoreEventsDiscardingMouseEvents:
discardMouseEvents,
I've scrolled to the left with my trackpad and then pressed the left arrow
key, and I got this:
# Meaning of array values by position
# 1, type (2 is keyboard)
# 2, timestamp
# 3, keyvalue
# 4, keypress or release
# 5, modifier keys

# Trackpad <-
[2, 833516, 123, 1, 15, 0, 0, 1]
[2, 833516, 28, 0, 15, 28, 0, 1]
[2, 833516, 123, 2, 15, 0, 0, 1]
# Left arrow key
[2, 963545, 123, 1, 15, 0, 0, 1]
[2, 963545, 28, 0, 15, 28, 0, 1]
[2, 963545, 123, 2, 15, 0, 0, 1]

This array comes from EventSensor>>primGetNextEvent: array which is a
primitive (94), so I think it's a problem in the VM, does someone know what
can we do?

Thanks,
Gastón
