I have a strange problem with my gui buttons.
Despite the button text being black and not grey(I think this means it is enabled) i cannot click them.(and by that I mean the buttons do not go into a pressed state.)
Also: this only occurs after I go off the main menu the first time. Some buttons do work on the 2nd menu and only the exit button on the main.

Sorry, that's too much code for me to understand what's going on without compiling and trying. And it's not enough code for just compiling and trying...
But the typical reason is that it doesn't get the focus (for example some invisible statictext being in front of it - that happened to me already a few times). So what you can do is check which element has the focus right when you click the mouse-button (IGUIEnvironment::getFocus()).

Yep their is an invisible statictext in front of it. Thanks.CuteAlien wrote:Sorry, that's too much code for me to understand what's going on without compiling and trying. And it's not enough code for just compiling and trying...
