Thanks for the suggestions! When you say it crashes with less than 3 collision points, how did you do that? Doesn't the 'delete' option become disabled when you have 3 collision points?
I think I explained wrong, I'll try to explain better. The error happened when I wore a png image 24, almost all transparent, but filled with only 3 pixels. I think it was this image:
<img src="http://filippileonardo.com/_contents/games/magi_v1/images/magi_magic_normal_sparks-sparks-011.png" border="0" />
Appeared a message saying it could give an error, can not remember how was the message. Then I closed the program, and when reopened, the message appeared saying it could not open because there was an image with less than 3 points of collision.
Sorry, the last days were very busy, I do not remember for sure the message, nor the image used for so many.
Thanks, and good work.
