I have had a problem since I've started using NGUI that just wont go away. It always happens without fail. I've followed tutorials on how to make a panel with alpha clipping and it works IF there is no slider. If I try to drag the slider the clipping re positions itself so it has -width/2 as center of the clipping area for no reason.
I even tried to update to the newest version hoping you fixed it (even though I've done the whole project in the version before 3 so upgrading is painful) to no avail. So I recorded a video of what happens:
http://youtu.be/lPt_dEwYKlkIt is driving me crazy, I can't have sliders or all my panels break! If I click reposition clipping in draggable panel the same thing happens. There is no reason reposition should do this!
Here is a screenshot of my panel settings, though I've tried adjusting every setting available to get it to work and the same thing happens.
If you have any questions (and I'm sure you will have) please ask. It is a show stopper for my project and I want it fixed ASAP.
