How do I set a TSpeedButton (on a TToolbar) to look pressed down? It's only highlighted when clicking but gets normal when the mouse leaves it. I set the property Stayspressed to True and indeed the property IsPressed becomes and stays True, but this state is not visible.

What style are you using? Some of the included ones do not have every effect included.
First, revert back to the windows style. If that works, then it's definitely a styling issue, rather than a code issue.
If you want to add an effect (actually an animation) to another style:
- Right click on a button and select Edit Default Style.
- Find the Fill.Color property of the Rectangle you want to show the anmimation.
- Click the animation icon and add a TColorAnimation
- Set: the StartValue (the existing value).
- The StopValue
The Trigger: IsPressed=True
Repeat the above to add a second animation with the Start and StopValues reversed and Trigger of IsPressed=False

This is a tough one - the standard TButton style includes effects which work - the button will look pressed when "IsPressed" is true. However, other styles (and especially your own) can be much more problematic. I have found the best solution is to have 2 styles and change the style when the button is pressed.
I found it pretty impossible to get "mouseover" animation to work with "pressed" animation in buttons - normally you want to highlight the button slightly when the mouse passes over and then add an effect when you press - especially when you don't want the default shadow effect but a colour effect (which I prefer, I don't like the inner shadow effect of a default button press), but I always seemed to end up with issues. Either one effect wouldn't fire OR the button state wouldn't return to what you'd expect (visually I mean).
My advice - add a little bit of extra code to change the style for the pressed button, you might go mad otherwise :-)
