There is an UI issue both reproducible with Kaivo and Aalto (Mac OS X 10.9.2, Ableton Live 9.1.1 x64): the patch menu auto-closes when you hover your mouse over the patch folders. When the patch folder submenu disappears, main menu closes as well.
This happens only if you open the patch menu on the first time after launching Kaivo/Aalto GUI.
Steps to reproduce:
- Load an instance of Kaivo/Aalto on Ableton Live MIDI track
- Open Kaivo/Aalto GUI
- Click on a drop-down menu to open patch menu
- Hover the mouse pointer down to the first patch folder ('Kaivo/Aalto keys' in my case): the patch folder submenu appears on screen
- Move the mouse folder out of the patch folder item (up or down): the patch folder submenu disappears, as well as the main patch menu.
It's interesting, that this happens only if you open the patch menu on the first time after launching Kaivo/Aalto GUI. So, if you repeat the same steps again the main menu will not disappear after disappearing of the patch folder submenu.
If you just close and reopen Kaivo/Aalto GUI the issue will be reproducible again.
Thanks very much for the clear description. One person was reporting this but I could never reproduce it. Now I have a better chance.
