Hi,
I'm using the Linux binary. Some buttons in the user interface take several seconds before any effect occurs. This is most notable when first starting up, eg the initial "Start" button, the login "Play Online" button, etc.

If these are implemented as real buttons, perhaps you could add an animation or something to show that the button has been clicked? If it is too hard to implement, perhaps you could change the mouse cursor to the busy/waiting spinning cursor until the next screen loads?

Thanks :)
