Weight paint Mode Navigation.

Am i the only one having problems with Weight painting navigation on newer builds?

this has been happening for a little while…
(i use Maya Keymaps) Navigation its totally unusable… WTH happened?

In my case the shortcuts for the new Gradient tool were overlapping my personal setting for rotate and pan view (ALT+LMB and ALT+Shift+LMB respectively).
After setting them properly all works fine again, for the little I have tried it.
