Any one else seen this issue.
I have a GUI window with a scroll view in it populated with GUILayout buttons. The horizontal scrollbar works fine but the vertical one only works when you click in the gutter, use the mouse scrollwheel or run in opengl mode. This is not much good for the web plugin though as that only runs in directx mode on windows.
So it works fine on the mac as that is always opengl. But importantly what it won’t do is let you click on it and drag the thumb button up and down.
I guess this is probably a bug in Unity, but please can you post your GUI code, just to check?
I’m still looking into it at my end, it seems to become an issue when I have long lists.
It’s going to be hard to extract a simple test case but if and when I can I will post a bug report.
If it is a Unity bug, it wouldn’t be the only problem with the scroll bars of the scroll view function. I recently bug-reported another big issue when using scroll view in combination with GUIStyle.none. Vertical scrolling doesn’t work if you have both horizontal and vertical scrolling in combination with GUIStyle.none for both bars (although this bug happens also on a mac). My theory is that there is something horribly wrong with the vertical scrollbar implementation ^^.
