Yeah, I was pretty certain since yesterday that I was going to purchase and I just wanted to see how far I can get with the demo version and if I run into anything that would disqualify NGUI. But your system appears to be the best out there right now for Unity, it's really inspired. Also I am soooo tired of spending days and days arranging UI controls in code.
I'd definitely recommend making the demo up to date, I'm sure I'm not the only one who makes their decision depending on their experience with the demo version.
Anyway, I debugged a while and I could not get it to work unless I turn off 'Ignore Time Scale' which is what's using the coroutine instead of LateUpdate. I didn't see a useUpdateManager checkbox in LagPosition of the full version. Looks identical to the demo version code.
