Buttons doesn't register clicks if held to long,

[minus]

When clicking a button, if the click happens fast it's registered, but if it's slow (i.e. the left mouse button is held down for a while) it doesn't register.

The way button clicking works in CEGUI is that we listen for the mouse up event (instead of the mouse down). This is the standard for pretty much all UI systems. There however seems to be a bug, perhaps in CEGUI itself, which makes it not registering the mouse button up event if too much time has passed since the mouse down event.
We'll have to investigate.

Those buttons are all single click enabled, so I'm guessing that you for some reason experiences it to be double click when it's really not.
One issue could be if your system is slow, and Ember is running at a very low frame rate, it might appear that mouse clicks doesn't register.

[minus (me-minus)]

Ember is playable when in a world (more than 30 hz).

If I press and hold down the mouse button, the color changes on the
pressed button.
When I then release the mouse button, the button color changes back to
'out' color.
So something happens, (mouse over effect?) but I think no click
event get sent from the button.

Updated description. I don't know how long time the button needs to be pressed to present this issue, but I don't think it's very long (some seconds). I'll have to investigate.

The cause of this was that we were listening to the wrong button element event. It's now fixed.

Nice!

I'll test the next release then.

minus, looking forward to check out the new world.
