When requesting for help, DO NOT upload your projects containing NGUI's source code. NGUI's source code is not open source. The first time you do it I will simply remove the link and refrain from answering the offending post.
The second time you do it, you will get permanently banned from this forum and I will no longer give you any support.
I'm sorry to be harsh, but use some common sense, please. You'd feel the same way if I posted your proprietary work in a public forum.
If you wish to provide your project and/or example of some kind, either post it without including the NGUI folder, or send it to me via email instead (support at tasharen.com).
Thank you!
