Generally this only occurs with Windows users when a windows service hides the menu bar.  Due to the number of services and the rarity of this issue, we have not determined  steps to unhide the text menus.

Menu's have keyboard keys to access most functions. Most functions are available within the main Crate Pro 6 windows.

To access the Zoom use your keyboard keys. This will keep your zoom level for the session. 

After selecting your zoom with your keyboard keys, click on any of the other modules to allow the window to snap to your new zoom level.
