So recently found a problem with 6D not starting voice tags in QR mode. I fixed it by doing the unpress event instead of the press event.
I though I was in the clear but on 600D the same problem shows up. I fixed it by using event 4C... then it turned out the zoom shortcut also stopped working.
Seems recent changes to GUI handling did something where its missing events. When I turn on event viewer I see all of them but for some reason ML gui isn't responding.
I pulled latest 600D nightly to see if it was my issue and its not. Zoom shortcut is dead there too. Also booting nightly I got 100MB shoot malloc.. so 4MB is still gone but seems like there is a discrepancy here too.
i think nanomad and i found the "bad" changesets
