Josh,
How about this issue with no change of disabled font color? Or am I doing something wrong?
Next case - I’m trying to create my own popping up numerical keyboard. At the moment I have something like this (pre-pre-alpha ;)):
Window.txt resource:
<Glide Version="0.2.1">
<Window Name="window" Width="320" Height="240" BackColor="000000">
<TextBox Name="Box" X="58" Y="32" Width="84" Height="32" Alpha="255" Text="base octave" TextAlign="Center" Font="2" FontColor="000000"/>
<TextBox Name="Box2" X="58" Y="80" Width="84" Height="32" Alpha="255" Text="bpm" TextAlign="Center" Font="2" FontColor="000000"/>
</Window>
</Glide>

Thread.Sleep(-1);
}

{
var box = (TextBox)_window.GetChildByName("Box");
box.ValueChangedEvent += BoxValueChangedEvent;
box.TapEvent += BoxTapEvent;
var box2 = (TextBox)_window.GetChildByName("Box2");

Please take a look at it, how can this be made better and how to solve some of the issues mentioned within comments.
Also for such purpose maybe it would be nice to make a rectangle with cornerRadius > 0 but still with gradient - or maybe an image with transparent corners as a keyboard background is a better (with better performance) solution to this issue.

Edit: after pressing the Clear and Backspace buttons the textBox is refreshing with noticeable delay. Well, I would be a good FEZ Turtle programmer x_x.
Edit2: No way, it’s because it is in debug mode and it takes time to print the exception info after parse fails! ^^’
