1) Is there an extention (or a built-in feature I'm missing) to pop up a warning dialog box? You know, the "Are you sure you want to do this?" kind. I'm wanting to, in my level editor, make one pop up on certain menu items that can be disasterous if used by accident.
2) With active picture, when I load a PNG file that has transparency, it changes RGB(0,0,0) to RGB(255,255,255). While not fatal in the editor, nor unbypassable, this would be quite annoying in the game, is there any way to prevent this?
(EDIT: Just to be on the safe side, I'll point out that this is loading from files at runtime, as it's possible to change the file used.)
