I really felt the best way to convey this was visually with a short video (18 seconds), you can find it here:
https://dl.dropboxusercontent.com/u/78881962/NGUIIssue.mp4Essentially I have 2 buttons attached to each my horizontal & vertical scrollbars. Left & Right arrow, Up and Down arrow, like you would have on any scrollbar. The problem is that when my scene first loads...the Right arrow button and the Down arrow buttons are missing. But if I pause and unpause, they mysteriously appear.
At first I thought...well maybe they are being drawn under my map, so then I disabled the map so that the interface was the only thing there and those buttons could not possibly be drawn under anything. No go, even with the map disabled, those buttons are still missing until I pause and unpause.
I cannot make heads or tails of this issue, so any help is appreciated!
