For future reference...

SOLUTION If soft-locked after clicking on the "Ease in" / "Ease out" text boxes:

First, keep menu button presssed while entering info into text boxes, then hit enter when finished & you can release the menu button.

Just keep it simple.

To prevent any accidental bugs when using the menu:

The binded smh menu button should be held at all times to keep the menu up.
The only times you SHOULD release the button is after clicking
the "Properties", "Load", or "Save" buttons because it won't let you click
in the pop up boxes if you have the binded menu button pressed,
that's when you should release the binded menu button to input whatever
into those new boxes you opened and the smh menu will close automatically,
leaving you with whatever properties or load menu you opened.

BUT, for the "Record" or "Settings" buttons,
you should keep the binded smh menu button held when you click those buttons,
to have them & the menu work as intended.

Hope this helps others as this little debugging adventure helped me.

Also thanks to the Dev for their lightning quick response times.
I was in another discussion topic and It was about 7:33AM in the morning and
the Dev responded to my 7:27AM message, we talked it through step by step
and we found the solution to this problem in less then half an hour!
We need more Devs like them! :)
