ImageButton not responding to clicks

[GoncaloRod]

I pretty much have the same issue has referenced in #92.

As you can see I'm giving each button a unique ID.
If I set button's texture ID to IntPtr.Zero all buttons start responding to clicks.

Well, found the problem, instead of binding the texture every frame (which can cause big memory consumption btw) I bind every texture in the beginning an store the IntPtr's in a collection. This not only fixed the button not responding issue but, also fixed my memory problems.
