Hand Tool/Help Menu Shortcuts Mixed Up
In their default states, the Hand Tool and Help menu options are bound to H and F1 respectively, but pressing H during normal use of the program consistently uses Help instead of the Hand tool.
Removing the F1 shortcut from the Help menu fixes this issue. I've experienced it in other areas, and I assume this solution will work for those as well.

After trying this several more times, the issue still remains. Removing the hotkeys for the Help menu does almost nothing to solve the problem.
