I've been using gimp for a while, and it was all fine until yesterday when I could no longer playback. When I click 'filters' or 'tools' (i can't remember which menu it was in) the playback button is not there.

The only thing i can think of that i changed is that i checked the box when it asks you a question when opening new images, causing it to no longer ask me whether I wanted to convert.

Does anybody know what is wrong and how i can fix it?

Thanks
