What operating system are you using?
How much memory do you have in your computer?
Do you have anything else running on the computer?
Was that artwork imported or created in Flash?
fire fox chorme etc
created in Flash..
I don't know. If the art was created in Flash then it shouldn't be a very large file. You created the art in Flash, yet when you try and place it on the stage, you get the out of memory message? If you save the file, how large is it? Is the character on object or is it made up of several smaller objects, for instance, is the trophy part of the main image, or is it separate?
