In previous TBV versions for windows OS the menu bar could have been not completely shown due to scaling issues. To resolve this problem please follow the steps below:
Reveal the menu bar
With Turbo-BrainVoyager in focus, press Alt, then tap the Down-arrow.
The menu bar should appear.
Shrink the menu-bar font
Press the Right-arrow until you reach the “?” (Help) menu.
Choose Decrease Menu Bar Font Size.
Repeat as needed until the menus fit and stop disappearing.
Alternate fix (Windows display scaling)
If the fix described above does not work, lower the global display scale:
Settings ▸ System ▸ Display
Set Scale to 100 % (instead of 150 % or another high value).
Turbo-BrainVoyager picks up the new scaling after a restart.
Both approaches should bring the File and other menus back into view.
