This is the menu.

STEPS TO REPRODUCE
1. Open menu with a keyboard button (like the "windows key" that I use as shortcut);
2. Press "up" or "down" to navigate the categories and them "right" to enter a category;
3. Press "up" or "down" to chose an entry.

OBSERVED RESULT
Instead of "up" and "down" select the entries inside a category it selects the categories. You can't navigate the entries to open the program you want.
Also, clicking with the mouse anywhere outside the menu doesn't close the menu.

EXPECTED RESULT
A- Pressing "up" and down" on step 3 would select the entries inside a category;
B- When the menu is open after you started to navigate on with, clicking with the mouse anywhere outside of it should close the menu? The menu can only be closed clicking on the menu buttom or pressing it's shortcut on the keyboard.
