I just update MW with the latest beta release, and it seems that the "problem" is solved! Many many thank you!!! The team is very fast! The scrolling/zooming is more smoothy and the last bar is actually sticky to the right of the chart. The only bug that I noticed, is that on Preferences/General/Mouse the mouse wheel action I set it on "Bar Width" with enable the "Invert" box, but don't seems that work properly. Before the update the invert works perfect. Maybe a little bug, I guess.. Anyway, congratulations for all the work
