Hi!
At first i did not know what is max height, then i realized i have to update gui to the latest version. simple importing from assets store worked, but it broke some other functionality (i have to investigate this further).
Also later i discovered that when i start a new project, and create new UI with NGUI on UIRoot i see new options, one of them is Max Height. Updating to the new version in the old projects did not reveal this new option, so i was wondering what you were talking about. can you confirm that this is not updated properly? since UIRoot does not reveal new options. Creating new UI in the old project does not reveal new options in the UIRoot
