I can't seem to get the mousemode "Z-translate selected models" to work properly. I have "translate selected" set to Alt+left-drag, so per the docs ("assigned button + Ctrl (in that order) switches to Z-translation instead"), Alt+Ctrl+left-drag should translate the selected model in Z. It does not, or at least in any reproducible manner.

Watch the selected yellow marker in the side view here on the right hand side:

1. Initially I translate in x-y using Alt-drag - works fine.

2. I try to translate in z using alt-ctrl-drag - nothing happens

3. I keep trying translate in z, and eventually it "works" - but if you look closely you will see that the movement of the marker is not synced up with the direction/speed of the mouse cursor.

Is this a bug? I remember testing this when it was initially implemented and I thought it worked fine so I suspect so...?

Cheers
