My UI works well using 3.1.
This is the second time I have tried to use 3.2.
In my first trial, my UI just crashed when use mouse.
using the latest build of 3.2, my ui has two issues:
1) UI response to mouse roll is not smooth sometimes!
2) Some element just gets disappeared while zooming. I have captured the following video. You can see that the RED circle gets disappeared while zooming out.
