A slight problem

This is very rookie i know but every time that I create a graphic /button it disipears…

I select it… > convert to symbol > select symbol (graphic /button) > hit enter and boom… screen goes blank. when i delete the symbol from the library i go back to the stage there it is (but as the original .gif or .jpg or whatever). Really annoying as I have in fact had this problem before but i can’t remember how i resolved it!

Any help would be much appreciated…

Well, what I think is happening is that you are creating a movie clip & it is going inside of the clip. If you double click outside of the main area it should go back to the main page where you can work with the symbol. Hope this helps.
