Velocity panel became hidden

[Djard]

I dragged the horizontal border of the Editor pane down, and now the panel at the bottom (where the velocity of notes can be adjusted) is stuck offscreen. If I scroll down, I can access the velocity panel; but then the toolbar up top becomes hidden. I tried dragging all the borders, headers and tried the View options but cannot restore the GUI to what it was. The velocity panel needs to be attached to the pattern editor to prevent this problem. Is there a way to move the velocity panel back up, so that both toolbar and velocity panel at bottom are accessible?
Attached is a screenshot.

Hmmm.. Looks more or less fine. The bottom-most panel is not attached to the pattern editor but just resides at the bottom. If there only a few instruments, it is expected to have a gap between the two.

The overall (right-most) scrollbar appears because Hydrogen was shrunk below its minimum size. If you enlarge the overall window, it should disappear again. If it is already on maximum size / full screen, you could check different values of Preferences > Appearance > Interface > High-resolution display scaling.

Thank you for your kind help.
